Connecting Trunks to LSM-4 Module Ports
This section provides information on connecting CO trunk cables for the LSM-4 module. For this
procedure, see Figure 5-2 and Figure 5-3 on

Use a patch panel at the rack and adapters between the patch panel and the Inter-
Tel 5000 Base Server. Use the fewest modular jacks and adapters as possible, and
do not attach any adapters to the back of the chassis; clearance issues prevent
them from attaching securely. If using a 6-pin, 6-conductor patch panel, make the
appropriate adjustments when using the adapters. You can also build your own 6P/
6C to 8P/8C patch cables, if necessary.
•
If using 4- or 6-conductor modular line cord, limit the length to 6 ft maximum. In
general, modular line cords are not twisted pair and could introduce crosstalk
between line 1 and line 2 at longer lengths.
NOTICE
Equipment Damage: Use adapters when connecting any 6-pin plug to an 8-pin
jack. Although a 6-pin plug will fit into an 8-pin jack, the plastic on the 6-pin plug
housing will damage pins 1 and 8 on the 8-pin jack. Not using adapters will
increase the likelihood of failure (to pins 1 and 8 in the 8-pin jack) should that
jack need to be used with an 8-pin plug in the future. Various adapter types are
available based on how you choose to connect to the patch panel.
