1. General

This practice is an installation and maintenance (I/M)
guide for the ADTRAN Fractional T1 Network
Interface Device (FNID). Figure 1 is an illustration of
the ADTRAN FNID.
Revision History
This practice has been reissued to reflect additional
support detail for two FT1 repeater applications.
The ADTRAN FNID is a network terminating unit
used to deploy a fractional T1 circuit using 2-wire
metallic facilities on CSA loops. This practice is
written to support both the T200 FNID circuit pack
(P/N 1245201L1) and the FNID standalone
(P/N 4245201L1) units.
The FNID is housed in a standalone metal enclosure.
The T200 FNID card plugs into a standard Type
200/400 multiple mounting shelf.

    Installation and Maintenance 1. General This practice is an installation and maintenance (I/M) guide for the ADTRAN Fractional T1 Network Interface Device (FNID). Figure 1 is an illustration of the ADTRAN FNID. Revision History This practice has been reissued to reflect additional support detail for two FT1 repeater applications.
  • Page 2: Installation

    With the exception of the physical dimensions of the units, the FNID and T200 FNID units are functionally identical. The FNID terminates local loop DSL signals originating from the Central Office (CO) unit and transforms the DSL signal into fractional T1 signals to be delivered to the customer.

    6. DSL DEPLOYMENT GUIDELINES The ADTRAN FT1 DSL system is designed to provide Fractional DS1-based services over loops designed to comply with Carrier Service Area (CSA) guidelines. CSA deployment guidelines are given below. . All loops are non-loaded only. 2. For loops with 26-AWG cable, the maximum loop length including bridged tap lengths is 9 kft.
  • Page 12: Troubleshooting Procedures

    2. Verify that the loop loss at 200 kHz is not greater than 36 dB. 3. Verify that noise on the DSL loop is within acceptable limits. 4. If Steps 1 through 4 pass and loop sync is still not available, replace the FNID. Section 61245201L1-5, Issue 3 7 a.m.

    Figure A-3. This loopback is initiated by the REM LBK button on the FNID, or by the craft interface when available. When the FT1 circuit is looped, all DS0s in use will be looped back toward the customer. All DS0s in use will be filled with all 1s and sent toward the network.
  • Page 15 The DS0s in use will also be transmitted on to the customer. There are two loopbacks available to the FNID. The FNID network loopback loops the FT1 signal back toward the network. The FNID CPE loopback loops the FT1 signal back toward the customer.
