E1-120 OHM LIM MODULE Variant of the E1 LIM (90-0568-01) which only supports 120 ohm interface. All other features of the E1 LIM are supported.

RS232/V.24 MODULE clei Single RS232 module providing for dual RS-232/V.24 interfaces per module. Most common synchronous and asynchronous speeds are supported up to 64KBPS. Both HCM and transparent framing formats are supported. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

MRD GEN/GEN 600 OHM MOD Manual Ringdown A-LAW Module with 600 Ohm resistive impedance. Tailored for Gen/Gen use only.

64K CO-DIR MODULE G.703 Co-directional DCM's. Two interfaces provided without signalling, one interface with ABCD signalling (software selectable). Either interface can provide system sync.

3630 SUPER-RATE RES MOD Module required to support X.21 <(>&<)> V.35 DCM speeds above 64 kb/s (n * 64K). For E1 3630's this module is required to support one or more super-rate ports. For T1 3630's the module is only required where more than one super-rate port is needed. This module is mutually exclusive with any other 36SMCP module (including Tone, DSP and VCB modules). For both E1 and T1 systems this module is required for 4602/46020 GUI support.

3630 2X4 VCB MODULE Digital voice conference bridge module with a maximum capacity of eight bridges. The eight bridges are partitioned into two groups of four, each group has a pool of 12 inputs which can be allocated as desired across the four bridges. This module is installed in the DSP slot of the 3630 and is mutually exclusive with Tone or DDS modules (90-0512-01, 90-0160-01).
