RAD DXC-30 Modular Digital Cross Connect D8SL - 2-wire SHDSL E1 Link Modules Simple Type: Network Hub / Switch / Router
D4SL and D8SL are four- and eight-port I/O modules that use Single-pair High-speed Digital Subscriber Line (SHDSL)technology, according to ITU-T Rec. G.991.2. Each port is a multi-rate SHDSL modem operating at user-selectable data rates that are multiples of 64 kbps (1 timeslot), up to 2048 kbps (32 timeslots). Payload capacity per module is up to 128 timeslots (8.192 Mbps) or 256 timeslots (16.384 Mbps). The D4SL/D8SL modules can be configured to operate in accordance with ITU-T Rec. G.991.2. Annex B, for compatibility with European (or similar) networks. Each port transfers either G732N or G732S multiframes (2 or 16 frames per multiframe, respectively). The user can also enable the CRC-4 option, specified in ITU-T Rec. G.704 and G.703, independently for each remote port. All ports can operate in unframed mode to transparently transmit unframed 2.048 Mbps signals. The modules can operate as a central SHDSL solution opposite RAD’s ASMi-52 SHDSL modems or FCD-IP and FCD-IPM access devices. The units also link with other vendors’ ITU-T G.991.2 compatible SHDSL remote terminal units.
