4.7 Optional Interface Boards
Optional Interface Boards permit the expansion of the external network and terminal interface
ports available in the eMG80 system are mounted on the Main board in the KSU or EKSU.
Interface boards available are shown in the chart below. Note that the boards that can be
installed in a KSU are dependent on the type of Main Board as discussed in section 4.5.
Table 4.7-1 Optional Interface Boards
CH204 2 CO Line & 4 Hybrid ports RJ45 & RJ11 2-wire
CH408 4 CO Line and 8 Hybrid ports RJ45 & RJ11 2-wire
CS416 4 CO Line & 16 SLT ports RJ45 & RJ11 2-wire
BH104 1 BRI & 4 Hybrid ports RJ45 & RJ11 4-wire & 2-wire
BH208 2 BRI & 8 Hybrid ports RJ45 & RJ11 4-wire & 2-wire
PRIU 1 PRI (30 channels) RJ45 4-wire
BRIU2 2 BRI (4 channels) RJ45 4-wire
HYB8 8 Hybrid ports RJ11 2-wire
SLB16 16 SLT ports RJ11 2-wire

The CO line ports of the Interface boards support loop start CO lines with detection of
supervisory signals including Caller Identification (CID), Polarity Reversal (PR), and Call
Progress Tone (CPT). The SLT interface of the Hybrid ports support FSK (ITU-T V.23 or Bell
202) or DTMF (ITU-T Q.23) Caller ID and the Message Wait Indication (MWI), DTMF
detection, sinusoidal ringing generator, -48V DC feeding voltage, current limiting and GR-909
Line Testing function.
