In the latter case, please contact your agent. 3.10 Router 2-Port CT1/PRI MIM 3.10.1 Introduction I. Router 2-Port CT1/PRI MIMmodule 1/2/4-port channelized T1/PRI interface module serves to transmit/receive and handle T1 data streams, provide CT1 access, and fulfill the function of ISDN PRI. Thereby, one card can be used for multiple purposes. II. 1/2/4-port fractional T1 interface module and module are different in the sense that: z FT1 operating mode supported by T1-F modules allows only one bundle. In other words, the time slots can only be bundled into one nx64 kbps or 56 kbps channel, where n=1-24. However, a CT1 module allows of arbitrary grouping of the 24 channels; z T1-F does not support PRI mode. 3.10.2 Interface Attributes The interface attributes of Router 2-Port CT1/PRI MIM modules are given in the following table: Table 3-26 Interface attributes of Router 2-Port CT1/PRI MIM and modules Attribute Description Connector RJ-45 2 Number of connectors 3-44

Step 1: On Router 4-Port ISDN-S/T MIM, choose the port for connection;
Step 2: Confirm the type of ISDN line provided by the telecom carrier;
Step 3: Connect the cable:
If the line is an ISDN U line, adapt it using an NT1 adapter by plugging one end of
the S/T interface cable to the S/T port of the NT1 adapter and the other end to the
BRI port on Router 4-Port ISDN-S/T MIM;
If the line is an ISDN BRI S/T interface line, directly connect the cable to the BRI
port on Router 4-Port ISDN-S/T MIM;
Step 4: Power on the Router, and check the LEDs of the corresponding slot on the
front panel: ON means that Router 4-Port ISDN-S/T MIM is operating normally and
OFF means that the POST of Router 4-Port ISDN-S/T MIM has failed. In the latter
case, please contact your agent.

Introduction
I. Router 2-Port CT1/PRI MIMmodule
1/2/4-port channelized T1/PRI interface module serves to transmit/receive and handle
T1 data streams, provide CT1 access, and fulfill the function of ISDN PRI. Thereby,
one card can be used for multiple purposes.
II.
1/2/4-port fractional T1 interface module
and
module are different in the sense that:
FT1 operating mode supported by T1-F modules allows only one bundle. In other
words, the time slots can only be bundled into one nx64 kbps or 56 kbps channel,
where n=1-24. However, a CT1 module allows of arbitrary grouping of the 24
channels;
T1-F does not support PRI mode.
