100 CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULES
Interface Cable MIM-1CT3 and MIM-1CE3 use the same type of interface cables and make
connection in the same way. For details, see “MIM-1CE3 Module” on page 97.
n
E3/T3 cables are not provided together with MIM-1CT3 and shall be prepared by
the user.
MIM-4BSE Module
Introduction MIM-4BSE, the four-port ISDN BRI interface module, transmits, receives, and
processes four channels of ISDN BRI S/T data traffic on ISDN BRI S/T interfaces.
The MIM-4BSE differs from the 4BS only in the way they set matched resistance
for an ISDN BRI S/T interface: the 4BS uses jumpers while the MIM-4BSE uses DIP
switches.
The MIM-4BSE can work in dial mode or leased line mode.
Interface Attributes The following table describes the interface attributes of the MIM-4BSE.
Table 59 Description of the LEDs on the MIM-1CT3 panel
LED Description
LINK/ACT ON means the carrier signal has been
received.
OFF means no carrier signal has been
received.
Blinking means data is being
transmitted or/and received.
LP/AL ON means the interface is in a
loopback.
Blinking means an AIS, LFA, or RAI
alarm signal is present.
OFF means no loopback or alarm is
present.
Note:
AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication
