Local Loop Connections for TDM Applications

Total Access 3000/3010 supports two types of local loop connections: copper pair and
optical fiber. All local loop connections are serviced through access modules.
1.7.1

Copper Loop Support

Copper pairs in Total Access 3000/3010 are delivered through 64-pin/50-pin AMP
Champ connectors on the backplane. Each slot has access to a total of eight copper
pairs, two of which are generally reserved for a DSX-1 network interface. Each of the
eight 64-pin/50-pin AMP Champ connectors delivers a single copper pair to each of
the 28 access module slots in the system.
The AMP Champs on the backplane are designated as follows: Pairs 1 through 4 are
generally local loop copper pairs. Pairs 5 and 6 can be a single DSX-1 network
interface (DSX-1 "B") or local loops. Pairs 7 and 8 are generally reserved for DSX-1
for each slot (DSX-1 "A"). See Figure 13 and Figure 14 for the layout of backplane
AMP Champ connectors for the Total Access 3000/3010.
This configuration supports the DSX-A as being dedicated, while Pairs 5 and 6 can be
routed to either the DSX or to the MDF.
