Cabling the CTPhone Controller
Step Procedure
1 Based on the size of your system, connect 8 or 16 pairs from
the telephone system analog line unit(s) to a connecting
block labeled P1 on the MDF. Pairs are shown in Table 3-B.
2 If your system has more than 16 CTPhone extensions, con-
nect another 8 or 16 pairs from the telephone system analog
line unit(s) to another connecting block labeled P2 on the
MDF. Pairs are shown in Table 3-B.
3 Punch down a second pair on the connecting blocks for
users that will have both wired phone and CTPhone handset
and connect them to analog line sets.
4 Connect cables to pair 20 (receive) and pair 21 (transmit) on
connecting block P1. Run the cables to the first base station
and attach RJ11 connectors to them.
See Table 3-C on page 3-6 for cable requirements. Note that
bridge taps are not allowed between the CTPhone Controller
and base stations.
5 Connect cables to pair 24 (receive) and pair 25 (transmit) on
connecting block P1. Run the cables to the second base sta-
tion and attach RJ11 connectors to them. See Table 3-C on
page 3-6 for cable requirements.
