LINE CARD DISTRIBUTION PANEL CABLE This cable is used to connect 27LC2, 27LC3, to (90-9634-01) 27LCx Distribution Panel, or 28LC, GSLC-12, and GSLC-16 to the (90-9634-02) 28LC/GSLC Distribution Panel.

LINE CARD DISTRIBUTION PANEL This is the distribution panel to connect the 27LC2 (90-1184-05) or 27LC3 (90-6396-01) to external circuits. The distribution panel connects to the line card via(90-9635-01) 27LC/28LC DISTRIBUTION PANEL CABLE. The 27LC2 requires one cable per card and two cards may utilize a single distribution panel. The 27LC3 require one cable and only one card may be connected to the distribution panel.

LINE VOLTAGE MODULE One per 3612 or 3630 required, if 48V signalling is required with LGS interfaces, or Vbat feed for E<(>&<)>M type 2 interfaces.

M/S TRAFFIC SHAPING MDL clei The 7470 Multi-Service Traffic Shaping Module (MTSM) is an optional module on cell-relay line cards designed to accept it (e.g. OC3-2). When installed it provides an additional 200K cells of buffering, per-VC queueing, per-VC shaping, ABR Virtual Source/Virtual Destination and other traffic management enhancements. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.
