1 UU is the universal cabinet number (1 for PPN, 2 - 3 for EPNs). C is the carrier
designation (A, B, C, D, or E). SS is the number of the slot in which the circuit pack
resides (01 to 21).
2Mbit Japan trunk (TN2242)
The TN2242 2Mbit, 30-port trunk circuit pack supports Japanese TTC private
networking environments. This circuit pack interfaces only with network
equipment or other circuit packs of the same model and is incompatible with all
other digital trunk circuit packs.
The maintenance strategy for the TN2242 is similar to that of the TN464F or later
suffix DS1 interface circuit pack. The TN2242 circuit pack is functionally the same
as the TN464F (without ICSU) with the following exceptions:
The Blue Alarm Inquiry Test (#139) always passes for the TN2242
The test ds1-loop command is not executed for the TN2242
When reset board is run on a TN2242, a different initialization message is
sent for the local looparound test (Test #135) is executed
Since an Integrated Channel Service Unit (ICSU) is not supported on this
circuit pack, tests associated with an ICSU are not executed,
Tests associated with new functionality available with the video-enabled
TN464F are not executed for the TN2242
Cyclical Redundancy Check (CRC) is not defined for this circuit pack
The D-Channel can be user-assigned to any port 1 - 30, when the signaling
mode is ISDN-PRI
Wideband is not supported
Stations (OPS) are not supported
The TN2242 circuit pack also supports specialized versions of CAS (Channel
Associated Signaling) and ISDN-PRI signaling that pertain to the TTC private
networking environment in Japan.
