Specifications
Capacity: 24 channels (“virtual” lines/trunks) for voice and analog data or for digital data only (T1); or 23 B-channels for voice and data, and 1 channel used for signaling (PRI). Supports networking in Release 6.0 and later systems, Hybrid/PBX mode only.
Mode: Multiplexes up to 24 channels into 1 facility and demultiplexes 1 facility into up to 24 channels.
Speed: Up to 64 kbps
Signaling: DS1 over 4-wire; Apparatus code earlier than 517M15, T1 uses robbed-bit or common-channel; apparatus code 517M15 and later, common channel is not an option for T1; PRI uses 23 B+D
Capacity: 4 loop-start lines/trunks for 2-way analog voice/data communication, 4 TTRs
Signaling: Loop-start
Capacity: 4 analog tie trunks. Supports networking in Hybrid/PBX mode only
Method of completion: Automatic start, immediate-start, wink-start, or delay-dial-start
Signaling: E&M type 1S, type 1C, type 5
