8.2 Analog Ports
The 24 available analog ports are associated with the voice channels and plug-in analog cards of the Access Bank II. The analog port status is activated upon entering the screen and displays the signal- ing bits associated with the card type and its signaling type configuration. The Analog Port Status screen allows the user to monitor the signaling bits in real time as it auto-reads the current status from the Access Bank II at specified intervals (you must be connected to an Access Bank II).
For each analog card the following data is monitored and described in the table below.
Name | Values | Comments |
Quiet Channel | 0=Off, 1=On | Idle/Active State |
Ringback | 0=Off, 1=On | |
Transmit "A" | 0, 1 | Signaling to network |
Transmit "B" | 0, 1 | Signaling to network |
Receive "A" | 0, 1 | Signaling from network |
Receive "B" | 0, 1 | Signaling from network |
Trunk Processing | 0=Off, 1=On | |
Self-test | 0=Off, 1=On | |
The contents and meaning of the signaling bits depends on the type of signaling used by the circuit provided over the channel. The Robbed-Bit signaling states for the following types of circuit signal- ing are provided in the tables below for the D4 (SF) and ESF framing formats. The types are:
•Loop-Start signaling
•Ground-Start signaling
