LCOB-8 Board
8-Circuit Loop Start (LCOB-8) provides all outbound and inbound call supervision on the
necessary circuitry for the connection of eight CO lines. The nominal impedance of each
CO line circuit is 600
.
DTMF, dial pulse, or a combination of both may be used for
outbound calls. Lines 1 and 2 of each LCOB-8 are connected to power-fail ports (on the
RJ-21X block) during power outages. All connections to the LCOB-8 are made through a
24-pin champ amphenol-type connector.

DTIB-8 Board
Each 8-Circuit Digital Interface Board (DTIB-8) supports up to 8 stations. Each station is
connected to the DTIB-8 through a single twisted wire pair. A single 24-pin champ
amphenol-type connector, located on the front panel of the card, provides the wiring to
the card. If the SLA box is used, for each digital station, two-analog stations are available..
