Figure 1. ADTRAN FNID
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.
