INSTALLING CORDLESS TELEPHONES
The Cordless Lite II/Cordless II phone allows for the connection of an optional keyset phone. The base unit
allows the user to switch between the Cordless Lite II/Cordless II phone and an Aspire keyset. Whichever
phone is activated at the base unit is the telephone which will ring. This allows you to have a keyset phone to
use while at your desk, and when you need to be away from your desk, you can carry the cordless phone
with you. Refer to
Cordless Telephone — P/N 730088/730087 (page 4-64) for more details on setting up
the phone and its optional equipment.
Cordless Phone Extension Cabling (Figure 3-3)
Each cordless phone extension requires a digital extension port with one-pair twisted station cable from the
MDF to the modular jack.
To connect station cabling:
1. Punch down one-pair 24 AWG station cable
for each cordless telephone to a cross-con-
nect block.
2. Punch down cross-connect from the clips on
the cross-connect block to their correspond-
ing clips on the extension (B) block.
3. Connect the extension (B) block's 25-pair
cable to the corresponding RJ-61 connector
on the PCB.
4. Install bridging clips on the extension (B)
block.
Installing a Cordless Telephone (Figure 3-3)
To install a cordless telephone:
1. Install a modular jack for each cordless tele-
phone. The modular jack should be within
six feet of the base unit.
2. For each extension, run one-pair 24 AWG
station cable from the cross-connect block to
a modular jack.
3. Terminate the extension leads to GRN/RED
of the modular jack.
Important
In some cases, when testing the operation of an exten-
sion port when connecting to a Cordless II, Cordless
Lite II, or 2PGDAD module, a technician may con-
nect a line cord directly from an extension port on the Aspire/Aspire S ESIU PCB or Aspire S CPU. Though
this is not the recommended connection, it can be used to check if the extension has dial tone.
Should a direct connection of this type be made to the base station of the Cordless II or Cordless Lite II, or to
a 2PGDAD module, the line cord must be 2-wire (1-pair). If a 2-pair wire is used, the system will provide
power to the unused pair. This can prevent the cordless telephone from acquiring a link with the base station
or it can damage the 2PGDAD module or the Aspire station card.
The recommended connection is to punch down 2 wires to the cross-connect block, then connect the exten-
sion block to the RJ61 connector on the PCB or CPU.
