2Mbit Japan trunk (TN2242)

The TN2242 2Mbit, 30-port trunk circuit p ack supports Ja panese TTC private
networking environments. This circuit pa ck interfaces only with network
equipment or other circ uit packs of the same model and is incompatible with all
other digital trunk circ uit packs.
The maintenance strategy for the TN2242 is similar to that of the TN464F DS1
interface circuit p ack. The TN2242 circuit pack is func tionally 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 l ocal looparound test
(Test #135) is executed when reset board is run on a TN2242.
■Any tests associated with an Integ rated Channel Service Unit (ICSU) are
not executed, since ICSU is not sup ported on this circui t pack.
■Any tests associated with new func tionality available with the
video-enabled TN464F are not executed for the TN2242.
■Cyclical Redundanc y Check (CRC) is not defined for this c ircuit 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 sup ports specialized versions of CAS (Channel
Associated Signaling) and ISDN-PRI signaling that pertain to the TTC private
networking environment in Japan.
