1.1 DSL Mode DSX-1-Fed System Application
NOTE
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 DSL Mode DSX-1-Fed configuration will be used when several technologies are
to be used with Total Access 3000/3010 and the shelf is to be DSX-1-Fed.
Currently, the technologies that can be mixed together into one DSL Mode DSX-1-Fed
shelf are:
• T1 (T1-OR)
• HDSL (HTU-C, H2TU-C)
• ISDN (HD-10 in 8 or 10 DSL mode)
The exception to the mixing of technologies is the ODS-2 (QFO-C). Due to the
configuration of the HD-10 in 10 DSL mode, the QFO-C cannot be accommodated in
this configuration.
When mixing technologies in Total Access 3000/3010, it is important to note the shelf
can facilitate a combination of up to 28/22 modules of T1-ORs, HTU-Cs, H2TU-Cs, or
up to 14/11 modules of HD-10s (8 or 10 DSL mode).
When different technologies are used in the same shelf, the wiring should follow the
DSL Mode DSX-1-Fed table (see Table 1). This assures the user that all technologies
reach the network via the DSX-1 connectors, pairs 7 and 8; and the loop via the MDF
connectors pairs 1 through 5. Table 2 is the pinout for pairs 7 and 8 for Total Access
3000, and Table 3 is the pinout for pairs 7 and 8 for Total Access 3010. See Table 4
and Table 5 for cable pinout details, for pairs 1 through 5 of the Total Access 3000
and Total Access 3010, respectively. See Figure 1 and Figure 2 for MDF terminal
block mapping. As long as these guidelines are followed, there is no specific ordering
of technologies or modules within Total Access 3000/3010.
NOTE
The H2TU-C delivers its HDSL2 signal to the loop on pair 2 only.
