Case Study – GL's NMS Deployment at United State Postal Service (USPS)
USPS outlined a request to replace existing test equipment and stressed that consideration must be taken to make the transition to the new equipment
as smooth as possible. A “plug and play” system, very comparable to the existing system was carefully designed.
GL's system for the USPS was designed to provide T1 and LAN testing and monitoring as illustrated in the figure above. The system comprised of intrusive
and non-intrusive line monitoring solutions. Salient features include -
- TDM Monitoring Solution monitors 600 T1 lines and over 100 LANs monitored
- SS7 & ISDN Monitoring Solution monitors 52 T1 E1 ISDN & SS7 with Voiceband Traffic
- SS7 Monitoring Solution monitors 56 T1 SS7 - still growing
- 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
- Customized software at probe and Webserver locations
Overview
GL's T1/E1 Network Monitoring System provides network wide management of T1 and E1 lines including line health, intrusive diagnostics, non-intrusive
monitoring, and much more. Maintenance engineers can securely access the network view from literally "anywhere" that Internet access is available. They
can also monitor, diagnose, and troubleshoot remotely with simple to use scripts.
- PC based T1 and E1 probes that collect physical and line level status and performance
information. The Intrusive and Non-intrusive "probes" for TDM networks are deployed at strategic locations in a network. They can transmit and collect
voice, data, protocol, statistics, and performance information. These probes can relay information to a central / distributed Network Management
System (NMS).
- A "T1 E1 J1 Switch" for non-intrusive monitoring or intrusive diagnostics; The switch is
"fail safe" during power disruptions and USB controlled by the PC that houses the probes.
- The NMS provides an instant overall graphical view of the health of the TDM network with drill down to individual lines; secure access through WEB;
remote monitoring and diagnostics to troubleshoot any T1 E1 line; and a central database and applications for controlling, collecting, and analyzing the
information provided by the various probes.
