2. SYSTEM COMPONENTS2.1 Shelf

Total Access 3000/3010 is composed of four main elements:

Total Access 3000/3010 Shelf and Backplane

System Controller Unit Module

Multiplexers

Access Modules

The system houses the management, multiplexer modules, and access modules. The

compact shelf includes all the features necessary for total system functioning including

provisioning, protection, monitoring, alarm status, and optical fiber routing. The single

multifunction backplane provides for a variety of system arrangements.

The Total Access 3000/3010 shelf is compliant with all applicable NEBS Level 3

requirements and listed to UL 60950.

All modules are inserted and removed from the front of the shelf. The far-left slot is

designated for the System Controller Unit (SCU), the next two slots are designated for

Multiplexer Modules, and the remaining 28/22 slots are reserved for access modules.

Slot openings are labeled for easy identification and the access module slots are

numerically linked for optional protection pairing.

The 6-inch high, 12-inch deep, 23-inch/19-inch wide shelf is constructed of heavy

gauge sheet metal with vent perforations on the top and bottom planes. Construction

provides for all standard wire runs. Reversible mounting brackets allow for flush

mount or 5-inch overhang configurations. Mounting brackets meet either the 1-inch or

1 3/4-inch mounting hole pattern (see Figure 1).

2.2 Heat Baffle and Fiber RoutingAn optional heat baffle mounts directly above the main shelf. The heat baffle is 4

inches high and 21.5/17.5 inches wide. It allows passage of cool air to convect heat

away from the shelf above the baffle. It also has a shallow trough in front to route fiber

optic cables from the shelf below the baffle. A separate fan module pulls air up and

across the shelf cards below the baffle. All elements fit in the standard 23-inch/19-inch

wide rack.

7-Foot Bay

Heat Baffle is 4 inches in height.

2.3 Bay ConfigurationsTotal Access 3000/3010 is available in a 7-foot bay configuration. The actual number

of services that can be provisioned from a particular bay depends on the type and

concentration of those services. Some arrangements draw more power than others and

may impact total power consumption to a higher degree. See Figure 3 for an example

of a six-shelf installation.


SYS-101Page 9 of 46


3. SYSTEM CONNECTIVITYThe multifunction single backplane is the key element in system versatility. It contains

all I/O connectors, control and signal routing, power input and ground, plus the

interconnections between access modules, multiplexer cards, and the SCU. There are

also facilities for plug-in modules and wire-wrap pins for special purposes.

See Figure 4.

Refer to Figure 4, (page 9) the Total Access 3000/3010 Backplane, to identify the

locations of the following:

3.1 System and Power GroundFlag A. Power Connections

The system is designed to accommodate redundant power configurations. Dual

Terminals for -48V and return are provided. The system will operate with either

individual supply or both supplies functioning.

Flag B. Frame Ground

Copper terminal block is provided for frame ground.

3.2 TimingFlag C. Timing Input

Total Access 3000/3010 operates in local, loop, or external timing modes. For external

timing modes, the unit accepts an optional daughterboard to terminate a 64K

composite clock at C1 and routes the timing signal to all modules. For SONET

applications, the shelf terminates primary (C2) and secondary (C3) DS1 1.544M

clocks and delivers the signal to the MUX common cards.

Flag D. Output Clock

Two external DS1 clock outputs allow Total Access 3000/3010 to source time other

communication devices. The shelf provides two output clock sources when a

multiplexer that supports this feature is installed.

3.3 Network Interfaces

NOTE

Total Access 3000/3010 can accept DSX and MUX signals simultaneously.

Flag E. Multiplexed Network Access

The high-speed multiplexed interface (DS3 or STS-1) is available through standard

coax cable connections. A BNC adapter, P/N 1181004L1, is required. All fiber

contectivity is accessed through the faceplate.

4.2 Multiplexer ModulesThe Total Access 3000/3010 can receive its network source either directly from the

DSX cross connect panel, or from a high-speed network feed such as a DS3, STS-1 or

OC-3 connection. Two multiplexer slots, labeled A and B, allow installation of high-

speed multiplexers. Utilizing one multiplexer provides a reliable, high-speed network

connection. Two multiplexers provide automatic protection switching capability; one

MUX is online, the other is in standby. The DS3 and STS-1 multiplexers get their feed

from an optional BNC connector on the backplane (labeled E in Figure 4). The OC-3

multiplexers have two fiber optic cables that connect behind the faceplate.

4.2.1 DS3 Multiplexer Module (P/N 1181020L2)The Total Access 3000/3010 DS3 Multiplexer serves as a DS3 interface into the

system via the optional RX/TX BNC module on the backplane. The DS3 multiplexer

terminates a standard DS3 signal (45 Mbps) from the network and converts the signal

into 28 DS1s (1.544 Mbps/ea) or seven DS2s (6.3 Mbps/ea) or any combination of the

two. See Figure 7.



The DS3 multiplexer module provides full grooming of payload DS1s. Any payload

DS1 can be routed to any access slot in the shelf.

The DS3 incorporates these features:

Screen provisioning and troubleshooting via menus or TL1 through the SCU

Performance history

Supports M13 or C-bit parity DS3 framing

4.2.2 STS-1 Multiplexer Module (P/N 1181030L2)The Total Access 3000/3010 STS-1 SONET Multiplexer provides a full STS-1

SONET multiplexer in a single slot of a Total Access 3000/3010 chassis. This single

1-inch wide card provides a SONET terminal multiplexer in an extremely small space

and includes time slot assignment for all VT1.5s delivered through the STS-1 network

interface. Redundancy is supported but not required, so the system can have either one

or two STS-1 multiplexers installed. If two are installed, they share the same network

interface, with one of the units active and the other in hot-standby mode. See Figure 8.

Up to 28/22 VT1.5s can be delivered through the STS-1 multiplexer. However,

installing the multiplexer does not eliminate the office repeater capability of the

system, so a single system can have an STS-1 and several DSX-1 network interfaces

simultaneously. Full DS1 time slot assignment capability allows any DS1 delivered

from a VT1.5 in the STS-1 signal to be delivered to any slot in the system. The DS1

can be delivered out of the system in many different forms, including repeatered T1,

HDSL and DSX-1 for local delivery of the DS1.




The STS-1 incorporates these features:

Screen provisioning and troubleshooting via menus through the SCU

TL1 and SNMP support via SLV

4.2.3 OC-3 Multiplexer Module (P/N 1181031L1)The Total Access 3000/3010 OC-3 Multiplexer transforms the Total Access 3000/3010

system into a SONET network element able to interface with industry standard

SONET equipment. The OC-3 module is a terminal mode SONET interface and

therefore deploys as a termination device subtending from a SONET ring. The first

STS-1 within the OC-3 is terminated on the shelf. The unit multiplexes and

demultiplexes the signal into 28 VT 1.5s. It provides full time slot assignment

capabilities, allowing any payload DS1 to be routed to any slot in the system. See

Figure 9.

The OC-3 module is capable of operating in a single or fully redundant configuration.

Full redundancy is achieved by configuring the modules in a protection-switching

mode in which the online MUX would transfer the payload to the off-line, or hot-

standby, MUX upon the detection of a fault condition. In normal operation, both

modules receive concurrent payloads from the network, while only the online module

transmits to the network. The linked provisioning option of the OC-3 module

ensures that both modules constantly have identical provisioning settings in the event

of a protection switch to the off-line module.

4.3 Access ModulesTotal Access 3000/3010 incorporates a complete array of local loop access

technologies into an integrated intelligent system. Access modules include those

servicing both optical and metallic local loops. Most access modules occupy one slot

in the Total Access shelf. Those devices that occupy more than one slot will be

specifically identified.

A 1:1 Automatic Protection Switching (APS) option will place two identical modules

in adjacent slots into an online/standby status. The main unit occupies any

odd-numbered slot and its auxiliary unit occupies the next higher even-numbered slot.

Failure events with the online loop or device will enable a protection switch.

Protection is not available on the double-wide HD-10 for ISDN.

To facilitate full integration, Total Access 3000/3010 technology is compatible or

identical in function with existing ADTRAN products. Screen displays and menus are

consistent with the look and feel of other ADTRAN displays to ensure operator

familiarity.



The access technologies and devices supported by Total Access 3000/3010 are listed

in Table 1. Refer to individual Installation and Maintenance Practices for detailed

information on installation, testing, operation, maintenance, and troubleshooting.

4.3.1 HTU-CThe Total Access 3000/3010 HDSL Transceiver Unit - Central Office (HTU-C) is a

central office transceiver unit that works with an HDSL Transceiver Unit-Remote

(HTU-R) and up to two HDSL Range Extenders (HREs) to establish T1 data rates over

the local loop. The unit is designed to operate in the shelf, which can accommodate up

to 28 HDSL circuits. See Figure 10.

The HTU-C functions as the host in a host/client arrangement, with the HTU-R and the

HRE as the clients. All of the HTU-C HDSL circuit parameters are configured in the

software. These parameters are then automatically communicated to the HTU-R upon

synchronization. The HTU-C can operate in MUX configuration (e.g. DS3-fed shelf)

or with direct DSX-1 input from the network.

The HTU-C has two span powering modes, and provides less than -140V for span

powering both a low voltage HTU-R and a low voltage HRE. For span powering two

low-voltage HREs and a low-voltage HTU-R, the HTU-C provides -190 Vdc.

The Total Access HTU-C provides comprehensive user-friendly Operation,

Administration, Maintenance, and Provisioning (OAM&P) circuit information for the

entire HDSL loop.

Built-in protection switching in the 1181106L5 HTU-C allows a service provider to

provision an HDSL circuit with a second HDSL circuit in hot-standby for redundancy

of both of the HDSL CO and remote line cards and copper facilities. The 1181106L4

does not contain built-in protection switching.

4.3.2 HD-10The Total Access 3000/3010 High Density-10 U Interface (HD-10) is a high density

circuit card that provides the functionality of an entire ISDN channel bank deployed

across a T1 carrier facility. The HD-10 is designed to provide the maximum

concentration for 2B+D Basic Rate interface (BRI) ISDN in a compact configuration.

See Figure 11.

The HD-10 accepts up to ten U interfaces and multiplexes them for T1 transport.

Conversely, the HD-10 can also accept a T1 line carrying ten multiplexed U

interfaces and demultiplexes them for individual deployments. The Total Access 3000/

3010 HD-10 operates in the industry standard 3xDS0 mode and is compatible with any

compliant ISDN channel unit such as the ADTRAN D4 U-BR1TE. The HD-10 also

supports the ADTRAN proprietary 4:1 Time Division Multiplex (TDM) format. When

deployed in the 4:1 TDM mode, up to ten 2B+D BRI circuits can be delivered,

providing optimized utilization of the T1 carrier facilities.

The receive transmission path of the T1-OR provides a long-haul regenerator followed

by a provisionable DSX pre-equalizer, and its transmit path provides a short-haul

regenerator followed by a provisionable transmit line buildout. It is capable of

Superframe (SF) to Extended Superframe (ESF) framing format conversion and

provides both DSX-1 and multiplexer position connections with appropriate switching

logic.

The T1-OR can read and store Network Performance and Report Messages (NPRM)

from span equipment and generate network performance and report messages toward

the network in the receive channel. The unit can gain read/write access to the ESF

facility data link to and from the span without affecting the payload.

4.3.4 QFO-CThe Total Access 3000/3010 Quad Fiber Optic - Central Office (QFO-C) is designed

to carry up to four asynchronous DS1 circuits over single mode fiber at distances

beyond 24 km. Two units, one at the central office and the other at the customers

premises, make up a complete system. The QFO-C occupies a single slot in the shelf,

but requires an odd/even pair of slots. The even slot must either be empty or filled

with a protect module. Its remote counterpart, the Quad Fiber Optic - Remote

(QFO-R), resides in its own remote two-slot shelf. The system can be provisioned for

single unit operation or take advantage of the Automatic Protection Switching (APS)

where one unit is online and a second is in hot-standby mode capable of carrying the

data load in the event of a line failure. See Figure 13.

Total Access 3000/3010

Figure 17. TDM Network Interfaces

5.1.1 DSX-1All access slots in Total Access 3000/3010 have access to DSX-1 network interfaces.

These make the system function much like a managed Office Repeater Bay (ORB).

The advantage of having DSX-1 network interfaces available to the access module

slots is in delivering services local to the system. A local T1 need not be multiplexed

to be delivered out of the system. Conversely, delivering a local T1 in a DS3-fed

system does not require using an extra slot.

Each slot has access to as many as four DSX-1 network interfaces. This allows for 1:1

protection and optical delivery of four T1s in an access module slot. If a QFO-C card

is installed in an odd slot, the next higher numbered even slot can only be used for 1:1

protection of this module.



5.1.2 DS3/STS-1Multiplexers are optional components of Total Access 3000/3010. Multiplexers can be

installed in the shelf after the other modules are installed and the system is up and

running. Multiplexers can be added after initial installation and provisioning, and

existing or new circuits can be served through the multiplexers.

The two slots designated for multiplexers are for redundancy. A single multiplexer can

support a fully loaded shelf with any technology combination. When two multiplexers

are installed, they function in a 1:1 protection arrangement. (This protection applies to

the multiplexer electronics but not to the coax cabling to the multiplexers.)

The DS3 or STS-1 multiplexer system requires the optional coax interface adapter

(BNC Module). This module makes the physical coax connection from the network to

the Total Access System. The field-installable BNC Module can be added at any time

after initial installation. Both multiplexers in a 1:1 protected system share this single

high-speed interface.

Installing a DS3 or STS-1 multiplexer does not preclude using DSX-1 network

interfaces. Access modules can derive their network interface from either the DS3 or

STS-1 multiplexer or from a built-in DSX-1 interface depending on how they are

provisioned. Total Access 3000/3010 can support a mix of these network interfaces

with some slots deriving their network interface from the multiplexers and other slots

from the DSX-1 interface.

The DS3 or STS-1 multiplexer incorporates full Time Slot Assignment (TSA)

capability for payload. Any DS1 or DS2 in the DS3 payload can be delivered to any

slot in the system. Therefore, if the first three slots use DSX-1 network interfaces, the

fourth slot can still deliver any DS1 in the DS3 or STS-1 payload.

5.1.3 OC-3The Total Access 3000/3010 system incorporates the option to have a SONET OC-3

multiplexer as the network source. The OC-3 multiplexer is a terminal MUX and

subtends off a higher order SONET ring. Unlike the DS3/STS-1 multiplexers

discussed in Section 4.4.2, the OC-3 MUX, when used in the Automatic Protection

Switching configuration, protects both the electronics and the path back to the SONET
