1.1.1
Introduction
This section provides step-by-step instructions for the configuration and turnup of an
HDSL Loop Support System (HLSS) circuit on an HDSL loop-fed from the network
via individual DSX-1. Configuration procedures include installing appropriate line and
remote cards, configuring the Total Access HTU-C cards for protection switching
operation and enabling the protection switching feature.
Protection pairs on the Total Access 3000 system are adjacent odd-even slots,
indicated on the Total Access 3000 front shelf screening. The odd slot on the left is
the MAIN circuit; the even slot to the right is the AUX, or backup circuit.
1.1.2
Prerequisite Procedures
Before beginning the configuration and turnup procedure described in this NTP, the
user should ensure that a Total Access 3000 shelf is properly installed and wired for
DSX network feeds. Also, ensure the SCU is installed and provisioned. Refer to
Shelf Installation in a Central Office
, for detailed procedures for either of
the above applications.
NOTE
Valid protection pairs are the adjacent odd-even slots in the Total Access 3000
shelf, and are further designated by the “brackets” on the lower front
silkscreen of the Total Access 3000 chassis. The left (odd-numbered) slot in
the pair is the MAIN; the right (even-numbered) slot is the AUX circuit for
the pair. Thus, Slots 1 and 2 are a valid protection pair, but
slots 6 and 7 are
not
. The pair must have the odd-numbered slot to the left in the pair.
NOTE
This procedure assumes that the technician turning up the protected circuit
knows which pair of slots has been assigned to the circuit, and that a single
DSX-1 signal from the appropriate source, generally a DSX cross connect,
has been routed and wired to the appropriate pairs of pins on backplane
connectors labeled Pair 7 and Pair 8. For a protected circuit, the appropriate
pin pairs that should receive the DSX-1 from the network are the odd
numbered pins corresponding to the MAIN, odd numbered slot. Details for
these connections are provided in
HDSL/T1-Only DSX-1-Fed
