T-1/E-1 Modem – Model 2361

When circuit performance and availability are a must and outages are not acceptable, the 2361 T-1/E-1 Fiber Optic Modem is the tool you need. A Bit Error Rate Test continually checks and reports the optical link quality. Comprehensive configuration, status and diagnostic management functions allow Tech Support personnel to rapidly identify problems. For protection against Modem problems and fiber outages the 2361 supports full modem redundancy. With the use of a special “Y” cable, your application attaches to redundant modems. Switchover is automatic on fiber cable or modem problems.

For mission critical applications and revenue protection, the 2361 meets and exceeds the demands made of it by Service Provider, Military and Commercial customers throughout the world. The 2361 allows quick problem identification and even helps anticipate troubles before they happen, keeping applications running and user satisfaction high.

2361 Application Overview

Reliable transport of user traffic is key to customer satisfaction. Just as important is the ability to meet a variety of applications and circuit configurations quickly and economically. The 2361 T-1 / E-1 Fiber Optic Modem has resiliency and flexibility built-in. With a variety of plug-in Single Mode, Multimode, 1310nm, and 1550nm optic options, the 2361 has optics fitting your needs. The 2361 supports Redundant Modem operation, protecting not only the Fiber Optic Path, but also Modem Hardware failures. Thus helping to keep those critical, must stay-up applications, up and on-line.

Mission/business critical traffic are often transport using T-1 / E-1 circuit. To minimize downtime, when these critical circuits are down, you need the ability to remotely configure, monitor status, and diagnose troubles quickly and without disrupting user traffic. The 2361's comprehensive management suite provides you the tools to keep critical circuits up and running. The 2361 implements Canoga Perkins' SideBand Management Channel (SBMC) for continuous management communication with the distant modem, or modems (redundant modem configuration). SideBand Management Channel resides outside the user data stream on the fiber, providing management communication without any disruption to the user's traffic. The monitoring and diagnostic features allow quick identification of problem origins. The 2361 performs a continuous Link Bit Error Rate Test to measure link quality. Network Control is instantly notified of degrading conditions and often able to correct the impairment before the condition gets severe enough to effect service. .

Management connectivity is key to redundant modem operation. Management communication paths between local modems and SideBand Management Channel allow all four modem to communicate with each other and coordinate actions. SideBand Management Channel operates on both fiber paths allowing full management communication even in the event of a fiber failure on one of the links. This provides Network Management Personnel full access and visibility at all times, allowing quick response to situations.

Whether your requirements are to enhance InfoSec/ComSec, to link voice, video or Internet traffic to District Headquarters, or to transport critical data over 100Km, the 2361's comprehensive management maximizes network availability and reduces problem resolution time and efforts. You get reduced CAPEX and OPEX costs, greater user satisfaction, and increased overall success.
