Trunk Installation
This section describes the installation process for terminating trunks to ADIX-VS trunk cards.
Inspect all system components before beginning the installation process.
Trunk Interface Cards Overview
Trunk interface cards are used to connect both analog and digital trunks to the system. Analog trunk
circuit can be programmed to accommodate either DP or DTMF lines.
CAUTION!
Do not remove or insert a circuit card while the ADIX-VS is powered up. ADIX-VS does
not support power-on maintenance.

FIGURE 35. TRUNK CARD INSTALLATION
Installing Caller ID Loop Start Trunks (VS-2CITK)
Caller ID loop start trunks are terminated to the VS-2CITK card. Each VS-2CITK card interfaces two
Caller ID loop start trunks to the ADIX-VS system. A maximum of three VS-2CITK cards may be
installed in the system.
Preparation
1. Set line loss with switches SW101-SW201. These switches are numbered in order of the trunk
circuits on the card. The factory default setting is 0dB.
2. Set the impedance of each circuit to 600 Ohms or 900 Ohms using switches SW102-SW202 .
3. Insure that fused are installed in locations F1-F4.
