 | DSX-1/CSU/RS I/F CARD Campus-RS CSU/DS1/DSX-1 interface modules install directly into a Campus-RS remote unit or Campus-RS Star concentrator and provide direct access to a T1 (1.544 Mbps) network. These interface cards, which feature fully integrated DSU/CSU capabilities, simplify installation and reduce the overall cost of ownership by eliminating the need for additional network access equipment. The Campus-RS CSU/DSX-1 (Channel Service Unit/Digital Service Crossover, Level 1) provides a cross-connection for "short haul" DS1 lines (up to 655 ft) and includes an alarm relay circuit. The CSU/DS1/DSX-1 cards meet all ANSI requirements for CI (customer installation) and NI (network interface) equipment. Both interface cards also provide line coding, line conditioning, equalization functions and support for local and remote (CO) loopback commands. The features of the CSU/DS1/DSX-1 interface cards reduce T1 deployment costs and can provide a "WAN gateway" connection for the local private enterprise network. price: $198.23 |
 | T1 MOD W/ CSU-DS-1/CSU-RS When installed in a Campus-RS Desktop Unit or a Campus-RS Star chassis, the Campus-RS CSU/DS-1 Interface Card (CADS1) allows the transmission of a T1 or fractional T1 data stream for up to eight miles over unconditioned twisted-pair copper wiring, using HDSL technology. The CADS1 terminates a long-haul T1 line on the customer premises. It provides maintenance jacks for T1 line monitoring and signal insertion. It provides line coding, line conditioning and equalization functions. The card responds to loopback commands sent from the CO as well as locally commanded loopback commands. The HDSL line can operate at either a T1 (1.544 Mbps) or fractional T1 (768 Kbps) rate. The front-panel LEDs on the chassis indicate the transmission status of the T1 line, the HDSL line and alarm conditions. price: $198.99 |
