ZXWR RNC Product Characteristic

High integration, large capacity, full

configuration of one million subscribers

needs only two racks.

All-IP configuration, various interfaces

Support ATM/IP dual protocol stacks.

Reduce the transp ort reso urc e by ATM-IP gateway

funct ion.

Easier evo lut io n to al l IP UTRAU by the rich

int erfaces su ch as IP ov er E1, ATM over E1/STM-1,

IMA E1/ch annelized STM-1, POS, FE, GE etc.
