SCP-FLC706-011-03H Description and Features
FLC-706 List 1A January 6, 2003 1
OVERVIEW
The ADC®PG-Flex®FLC-706 List 1A ISDN Basic Rate Interface Central Office Channel Unit provides an
interface to North American ISDN Basic Access services through a PG-Flex COT shelf. The FLC-706
accommodates four ISDN channels and provides ISDN Line Unit Network Termination (LUNT) at the COT shelf.
The FLC-706 installs into a single slot of a PG-Flex COT shelf.
DESCRIPTION AND FEATURES
The FLC-706 features are:
•four ISDN U-interfaces
•MLT compatible and metallic test access
•Vdc resistive test signature
•mp/pp-eoc slave mode in 3-DS0 format
•segmented path performance monitoring
•interim path performance monitoring
•software provisioning
•loopbacks
•Pair Gain Test Controller (PGTC) compatible
Operational Capabilities
The FLC-706 supports two-wire DSL 2B+D data or subsets of that rate. The B1 and B2 channels carry digitized
voice and data. The D channel communicates control signalling 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.
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 kΩfor out-of-service system tests

Description and Features SCP-FLC706-011-03H

Applications
ISDN is a networking standard that provides end-to-end, simultaneous handling of digitized voice and data traffic
on the same link. Figure 1 shows a typical ISDN configuration. The FLC-706 connects an ISDN Digital
Subscriber Line (DSL) to the Central Office (CO). Line Termination (LT) in the CO occurs at the ISDN switch.
The DSL loops are U-interface. The FRC-756 provides Line Unit Line Termination (LULT) at the RT. The
subscriber site has the Network Termination (NT1).
Figure 1. Typical ISDN Configuration
Set all options for the FLC-706 through the PG-Flex COLU or PGTC unit RS-232 maintenance port. Disable
ISDN by means of the maintenance port to prevent time slots from being assigned when they are not in use. The
FLC-706 must be plugged into a COT shelf before any ISDN provisioning screens can be displayed.
To provide clocking to the FLC-706, ensure the following conditions exist:
•a composite clock on the PG-Flex COT shelf is connected and correctly terminated
•an FPI-729 or an FAU-728 List 2 card is installed

INSTALLING THE FLC-706 IN THE COT SHELF
Insert the FLC-706 into the COT shelf. Ensure the LEDs go through the following sequencing:
•turn ON for about 2 seconds
•turn OFF for about 2 seconds
•scan ON from top to bottom
•turn OFF
If the LEDs do not follow the above sequence, see Table 2 on page 7.
Provisioning the FLC-706
Provision the FLC-706 using a List 3 or higher COLU practice. Access the ISDN Channel Setup menu and select
the appropriate options.
Verify operation
Verify incoming and outgoing calls for both B channels, where B1 is the digitized voice channel and B2 is the
data channel:
Outgoing calls
Verify outgoing calls for both B channels, for example, calls from the NT1 to the LT (refer to Figure 1 on page 2):
1Originate an outgoing B1 voice call and make sure that:
adial tone is present
bthe number you called is displayed (when answered)
the number from which you called is displayed as the originating number
2Hold up the B1 voice circuit, then switch to the B2 data circuit.
3Originate an outgoing B2 data call to the data loopback (LPBK) test line and perform the BER test (after the
data call is established).
4After the B2 data test is completed, drop the B2 data line, then drop the B1 voice line.
5Return all circuits to normal.
When verifying the B1 and B2 channels, only the B channel used for digitized voice has dial tone. The data
channel does not have dial tone.
To verify the operation steps, use a Tektronix Craftec CT-100 ISDN type test set (or equivalent) that can
generate a PRBS/2047 pattern to perform a data Bit Error Rate Test (BERT) when the circuit connects
to the far end. This is the most stressful pattern for ISDN circuits. A test result that does not exceed 10-7
BER must be demonstrated.

lncoming calls
Verify incoming calls for both B channels, for example, calls from the LT to the NT1 (refer to Figure 1 on page 2):
1To test an incoming B1 voice call:
adraw dial tone from another ISDN or POTS circuit
bdial the ISDN B1 voice circuit number
cverify that the number you called is displayed (when answered)
verify that the number from which you called is displayed as the originating number
2Hold up the B1 voice circuit, then switch to the B2 data circuit.
3Originate an outgoing call on the B2 data circuit using another ISDN data circuit and call the B2 data circuit
under test. Then, perform the BER test.
4Drop the B2 data line after the B2 test is completed. Then drop the B1 voice line.
5Return all circuits to normal.
