Set all options for the FLC-706 through the PG-Flex COT Line Unit or PGTC unit RS-232
maintenance port. Disable ISDN via the maintenance port to prevent time slots from being assigned
to them when they are not in use. The FLC-706 must be plugged into a shelf before any ISDN
provisioning screens can be displayed.
4.3
To provide clocking to the ISDN FLC-706 Channel Unit, ensure the:
_
composite clock on the PG-Flex COT shelf is connected and properly terminated
_
FPI-729 card is installed
_
FAU-728 List 2 card is installed
5. Operational Capabilities
5.1
The FLC-706 ISDN Channel Unit supports two-wire DSL 2B+D data or subsets of that rate. The
B channels (B1 and B2) carry digitized voice and data. The D channel communicates control
signaling and low-speed, packet-switched data.
Segmented path performance monitoring collects the error rates for each DSL loop individually.
Interim path performance monitoring collects the end-to-end error rate for the entire transport path.
5.2
For system isolation and system tests, the FLC-706 provides:
_
a hybrid transformer that isolates the equipment from the facility and provides coupling and
impedance matching at 135 Ω
_
metallic test access through the FPI-729 PGTC Interface Unit
_
MLT compatibility
_
a DC resistive test signature of 120 kΩ for out-of-service system tests
5.3
The FLC-706 meets the following requirements:
_
ANSI T1.601-1992 Layer 1
_
TR-NWT-000397 ISDN Basic Access Transport System Requirements
_
TR-NWT-000393 ISDN Basic Access Digital Subscriber Lines
_
TR-TSY-000829 Embedded Operations Channels
C. INSTALLATION AND TEST
6. Unpacking
6.1
Upon receipt of the equipment, visually inspect it for signs of damage. If damage is observed,
report it immediately to the transportation company and PairGain. Order replacement equipment
if necessary.
6.2
Check the contents against the packing slip to ensure complete and accurate shipment. If shipment is
short or irregular, contact PairGain as described in Section 10.3. If you must store the equipment for
a prolonged period, store it in the original box.
