BITS Timing Configuration
After connecting the BITS interface to the BITS, you must use the CLI to configure the type of timing signal
being supplied to the SPIO. Options include:
•
E1 Frame Alignment Signal (FAS)
•
E1 Multiframe with CRF (FAS+CRC)
•
T1 Extended Superframe Format (ESF)
•
T1 Superframe Format (D4)
For additional information on BITS configuration, refer to the
BITS Port Configuration Mode Commands
chapter of the
Command Line Interface Reference
.
Connecting to the CO Alarm Interface
The Central Office (CO) Alarm interface utilizes a 10-pin Molex female-connector fro interconnection with
the three normally closed dry-contact relays. These relays trigger external audio and/or visual indicators for
the following three alarm levels:
•
Minor Alarm:
This alarm is triggered when a high temperature is detected on a card, causing the fan
tray to switch its fans to high speed.
•
Major Alarm:
This alarm is triggered by a:
•
Hardware failure that places a card in an off-line state
•
Power filter unit failure or removal from the chassis
•
Failure of one or more fans on either the upper or lower fan tray
•
Fan tray failure or either fan tray assembly is removed from the chassis
•
Critical Alarm:
This alarm is triggered when a severe degradation in service is detected. For example,
if the system is supporting a large number of subscribers and packet processing cards are removed thus
significantly reducing the amount of available CPU and memory resources.
The CO alarm interface pinout is provided in the following figure and table.
