The SLIB is available in two (2) models, the SLIB 12 with 12 analog Single Line Telephone ports and
the SLIB24 with 24 SLT ports. In both cases, the SLT ports are each terminated in an RJ45

and support the Message Wait Indication, DTMF, or Pulse Dial signaling, Polarity reversal, sinusoidal
Ring generator, and GR-909 Line Testing.
