Installation and Programming
Analog Services Unit
This procedure applies to the ASU, the Universal ASU, and the ASU II
(compatible only with Release 7.0 or later software). Ensure that there is a
free CIM port on the controller.
ASU II mounting instructions:
For rack mounting (rear or front facing), do not install the feet.
For wall mounting, install only the two bottom feet.
All ASUs:
1. Mount the ASU. Refer to page 221 for ASU II line card installation
instructions.
2. Connect a Crossover Category 5 cable with RJ-45 connector to the
CIM port on the ASU and a free CIM port on the controller (see
Table 33 on page 256).
3. Complete telephony cabling for the ASU (see Table 42 on page 263).
4. For the Universal ASU, complete the Music on Hold and Paging
cabling if required. See Table 44 and Table 45 on page 265.
5. Connect power to the ASU. Once the CIM link synchronizes, the CIM
LEDs turn on. The controller detects the ASU, and the application
software downloads and starts immediately.
6. Using the System Administration Tool, program the ASU settings on
the controller. Refer to the System Administration Tool Help for
instructions.
Next: Install any other required services units. When all the services units
are installed, go to “Install Telephones” on page 64.
Tip: The ASU can be located up to 30 meters (100 feet) away from the
controller. The interface uses a single standard 8-pin modular jack consisting
of 2 balanced signal pairs, and is located on the front of the unit.
Tip: The ONS circuits provide positive disconnect for support of applications
such as door phones.
Tip:Use the LSMeasure Tool to determine the line settings for LS trunks on
an Analog Board or a Universal ASU (refer to the System Administration Tool
online Help).
