1.1 Standard MUX-Fed System Application
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The "a" represents the Total Access 3000 parameter
and the "b" represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed "28/22."
1.1.1 Usage
The standard MUX-Fed configuration will be used when several technologies are to be
used with Total Access 3000/3010 and the shelf is to be MUX-Fed.
Currently, the technologies that can be mixed together into one MUX-Fed shelf are:
• T1 (T1-OR)
• HDSL (HTU-C, H2TU-C)
• ISDN (HD-10 in 8 or 10 DSL mode)
• DSX-1
If the total Access system is being used as an M13 MUX, that is dropping off
up to 28 DSX signals from a MUX network feed, then connect pair 7 and 8
to the DSX cross connect as indicated in Table 1. Do not connect any of the
other pairs to the MDF. If the total Access system will employ both DSX-1
and access modules and other loop technologies such as T1 or HDSL, then
connect all the connections indicated in Table 1. If the Total Access system
will not employ any DSX-1 or access modules, do not connect pairs 7 and 8
to the DSX cross connect.
The QFO-C does not currently have MUX-Fed capability.
When mixing technologies in Total Access 3000/3010, it is important to note the shelf
can facilitate up to 28 modules of T1-ORs, HTU-Cs, H2TU-C, and DSX-1. The
capacity for the HD-10 in 8 or 10 DSL mode is 14/11 because the module is a double-
wide unit.
When different technologies are used in the same shelf, the wiring should follow the
Standard MUX-Fed table (see Table 1). This assures the user that all technologies
reach the network via MUX connectors (RX and TX), and the loop via the MDF (pairs
1 through 5). See Table 2 for cable pinouts for pairs 1 through 5 and Figure 1 for
MDF mapping. As long as these guidelines are followed, there is no specific ordering
of technologies or modules within Total Access 3000/3010.
