12.1 Module position and circuit identifiers
For NMTI purposes, module positions and circuits have alphanumeric identifiers.
Table 12-1 lists the formats and ranges, and gives examples. For example, P2-28
identifies circuit 28 on the primary rate module in module position P2.
For interface modules, there is a logical mapping between their physical positions on
the Control card (1 and 2) and their NMTI identifiers. Physical position 1 maps to
logical position M01 on the NMTI; physical position 2 maps to logical position M09.
Thus, all NMTI operations pertaining to position 2 are performed through logical
position M09. For example, the second circuit on an RS-232 DCM in physical
position 2 is identified by M09-2 (or 9-2).
Logical module positions M02 to M08, and M10 to M16, are not user-configurable
because they are not physically present. They are automatically reserved by the
2902 MainStreet system when a module capable of super-rate speeds over 128 kb/s
(that is, an X.21 or V.35 DCM) is configured in logical positions M01 or M09 (see
section 12.2 for more information).
Table 12-1 Module position and circuit identifiers
Notes
(1)
The latter form, < pp >, is usually used.
(2)
The DSP module position is not user-configurable and is configured for a super-rate module by
default.
(3)
A thirty-first circuit is available if CCS is selected as the frame type.
Figure 12-1 locates the positions for the primary rate and interface modules on the
Control card.
