5.4.2 SLIBC (Single Line Interface Board w/RJ21)
The SLIBC is available in two (2) models, the SLIB12C with 12 SLT ports and the SLIB24C with 24
SLT ports. The SLIBC is identical to the SLIB except the SLT ports of the SLIBC are terminated in a
25-pair RJ21 female connector. The SLIBC provides FSK (ITU-T V.23 or Bell 202) or DTMF (ITU-T
Q.23) Caller ID function to the SLT. The SLT ports provide the -48 VDC source, current limited to 20
mA, to operate the SLT and support the Message Wait Indication, DTMF, or Pulse Dial signaling,
Polarity reversal, sinusoidal Ring generator, and GR-909 Line Testing.
