Interface cable
The MIM-1G.SHDSL module uses regular telephone cables for connection.
Telephone cables have been included in the standard shipment package of MIM-1G.SHDSL.
Connecting the interface cable
You only need a telephone cable to connect one port on a G.SHDSL module to the PSTN network.

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.

Jumper settings
The MIM-4BSE uses jumpers to set matched resistance for ISDN BRI S/T interfaces. The use of
100-ohm resistance on an ISDN BRI S/T interface depends on jumper settings. The following figure
shows the jumper settings, where all the ISDN BRI S/T interfaces are using 100-ohm resistance.
