USPS Deployment Details:

• 600+ T1 lines monitored simultaneously

• 70+ PacketScanTM monitoring locations

• Customizable views per site, per link, per problem

• Real-time and historical alarm displays

• Intrusive T1 BER testing using T1E1 Switch

• Quick T1 E1 J1 Switch hardware development specifically for USPS

GL's solution for USPS features an instant overall view of the health of the entire network with the ability to successively drill down to individual T1 lines.

Maintenance engineers can securely access the network view from literally "anywhere" that Internet access is available. They can also monitor, diagnose, and troubleshoot any T1 line remotely with simple to use scripts. The system can also monitor USPS's "Ethernet" traffic at all USPS hub locations.
