Multifunctional Interface Modules (Router 5000)

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:

z

z

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.

3.10 Router 2-Port CT1/PRI MIM

3.10.1Introduction

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;

T1-F does not support PRI mode.
