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.

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 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.
■
A different initialization message is sent when the local looparound test
