RAD DXC-30 Modular Digital Cross Connect DE1B - E1 Link Module Simple Type: Network Hub / Switch / Router
DE1B is a two-port E1 link module for use with RAD’s modular Digital Cross-Connect units DXC-8R, DXC-10A, DXC-30, and DXC-30E. Each module provides two E1 links over copper or fiber optic interfaces that support both E1 and fractional E1 rates. DE1B can be ordered with either a balanced copper or a fiber optic interface. The following fiber optic, laser link options are available: 850 nm multimode 1310 nm single mode 1550 nm single mode, providing the maximum range of 100 km (62 mi). DE1B supports 2 or 16 frames per multiframe (256N or 256S), user-selectable TS multiframe with CRC-4 option, and 2 Mbps unframed mode per ITU-T Rec. G.703. Modules with copper links have two jumper-selectable line interfaces available: 120O balanced interface terminated by an RJ-45 connector 75O unbalanced interface terminated by two BNC female connectors. DE1B modules support two types of redundancy: Single-slot/line redundancy (1:1) ensures protective switching between ports on the same module within less than 50 ms. Y-cable redundancy switches between different modules to protect the service from hardware failure. This type of redundancy is supported by the copper interface only. For longer range applications, copper link modules are available with an LTU option that extends the receive level to –40 dB. The optional port bypass feature ensures continuous traffic support in case of power failure, by bypassing port 1 to port 2. Two user-programmable timeslot routing modes are available for the module ports: Bidirectional with symmetrical routing.Unidirectional with independent control over routing in each direction. Setup, control, and diagnostics can be performed via a supervisory port using an ASCII terminal or by the RADview SNMP element management system. Remote units can be controlled using a dedicated managementtimeslot in the E1 path. Diagnostic capabilities include self-diagnostics on power-up, local and remote loopbacks on each port, BER test on the active timeslots, and the inband code-activated loopback, specified in ANSI T1.403.
