2.2.2.1 UCM-ASLM
The UCM-ASLM (Analog Subscriber Line Gateway Module) provides analog interfaces between SLTs (Single
Line Telephones) and iPECS UCM System. It consists of 32 SLT line interface circuits and a LAN interface
circuit.
It supports -48V DC power feed, ring signal supply, CID (Caller ID) transmission and DTMF dial signal
detection for SLTs. The UCM- ASLM Gateway Module supports message waiting signal generation and 5 REN
(Ringer Equivalence Number).
Maximum SLT installation distance is 8Km (26,000 feet) in case of using AWG24 or UTP5 cable.
Maximum capacity (Voice data length per packet)
