Description
6NH7700-4AR60
Connecting cable with RJ-12 and RJ-45 Western plug to
connect an MD4 modem (RJ-12) with an ISDN-S0 outlet
(RJ-45). The cable is also suitable for an MD4 integrated
in a TIM.
Cable length 6 m
Note
It is best to hold the cable just below the RJ-12 plug. This makes it easier to insert the plug
than if you hold the RJ-12 plug itself. When inserting it, make sure that you can hear the RJ-
12 connector click into place!

mentioned above.
