Connecting Lines and Extensions
Use the following procedure to connect lines and extensions:
1 Test for a dial tone at the network interface jacks before connecting outside
lines to the control unit. For the test, connect a tip/ring telephone to the first
network interface jack.
a Lift the handset and listen for a dial tone. (If there is no dial tone, contact
your local telephone company before continuing.)
b Repeat for each network interface jack.
2 Connect line cords to the line jacks on the modules. Start at the top with the
line jacks on the processor module, and then move to the leftmost module.
Fill each module before moving to the next module to the right.
3 Route each cord through the wire manager on the front of the module.
4 Connect the free end of each line cord to the appropriate network interface
jack.
5 Test the lines by plugging a system telephone into extension jack 10. Press
the line button for each outside line and listen for a dial tone.
6 Test the extensions by doing the following:
• Plug a system telephone into the first extension jack on each module.
• Press the line button on the telephone for each outside line and listen for
a dial tone.
7 Connect modular telephone cords to the extension jacks, starting at the top
extension jack on the processor module. When that module is full, move to
the leftmost module. Fill each module before moving on to the next module
to the right.
8 Route each cord through the wire manager on the front of the module.
9 Connect the free end of each modular telephone cord to the modular wall
jacks for system extensions.
If extensions are not wired to any modular jacks, call a qualified service
technician.
