Applications

The TC1630R/S Fiber Optic T1/E1 Modem is typically used to link Channel Banks, PBX's, and M13 Multiplexers to DSX-1 Cross Connects.  It is also used to link Customer Premises Equipment to CSU/DSUs and with metallic medium T1/E1 multiplexers to transmit over fiber optic cable.

Description                                        

Intended as a highly reliable link between two T1/E1 devices, the TC1630R/S T1/E1 Fiber Optic Modem is available rack mount or standalone, in both multimode and single mode (850/1300/1550nm) versions.

The TC1630R/S provides a wide variety of innovative and standard features to benefit its users. Innovative features include Terminal Block and RJ-45 connectors, “hot-swappable” cards, 22 diagnostic LEDs  long distance version to 80km (1550nm, Single Mode), and an extreme temperature (-20^oC to 70^oC) version (TC1630T).

Standard features include Multiple Power Options (12/24/-48VDC & 115/230VAC), No Jitter, Power Redundancy, Optical redundancy (optional), Local & Remote Loopback, Low Current Consumption (200mA), Local Dry Contact Alarm Relay and a replaceable Line Interface Module.

The 22 different diagnostic LED functions include all 1’s detection, Power Alarm, T1/E1 Signal Loss (local & remote ends), BPV violations, and Sync Active. Eight DIP switches, accessible from the front panel, provide line settings for line code, line length, local loopback or remote loopback.  An intelligent line code setting switch is provided to eliminate potential user confusion, such as mismatching a line code/line length setting.

The TC1630R/S is transparent to the framing format and supports AMI, B8ZS and HDB3 line codes and DSX-1 (T1) cross connect distances from 0 to 655 feet.  It includes an internal elastic buffer to remove jitter from transmit data.

The TC1630R/S is compatible with all popular sizes and types of fiber optic cable.  Fiber optic connectors are ST or FC.  Electrical connectors are detachable Terminal Blocks and RJ45 (RJ-48C). 

The TC1630R Card version is used with the TCRM192 Rack Mount Card Assembly which can hold up to 10 modems.  Cards can be removed or installed under power (“hot-swappable”).  Two TC1630R Modems can be used with the TCRM196 19” 1 “U” High Rackmount Card Cage.

Note: TC1630R/S is 100% compatible with the TC1620R/S, its predecessor.
