SLTM32

The thirty-two (32)-port Single Line Telephone Module (SLTM32) allows standard analog Single
Line Telephone (SLT) devices access to CO Lines, other stations, and most features of the
system through the use of "dial codes". The SLTM32 provides interface circuitry for thirty-two
(32) SLTs. Each interface supports appropriate speech codec and compression functions, 36 volt
DC feed circuit; pulse and DTMF dial signal detection. A ring generator and message wait
circuitry are integrated in the SLTM32. The SLTM32 supports T.38 protocol for Fax over IP.
The SLTM32 allows Single Line Telephones to be connected up to 3 Kilometers (9,800 feet) from
the gateway using 24 AWG wire.
The SLTM32 includes a 10/100 Base-T Ethernet interface as well as packet voice processing
functions. The Ethernet port incorporates auto MDI, MDIX switching, therefore, both straight and
