Standard connecting cable for the integrated MD2 modem
The connecting cable 6NH7700-2AR60 is supplied with every TIM module with an integrated
MD2 modem. This allows the MD2 modem integrated in the TIM to be connected to an
LTOP overvoltage protection module. The actual connection of the dedicated cable is on the
LTOP overvoltage protection module using screw terminals.
The connecting cable can also be ordered as a spare under the number shown.

Standard connecting cable for the integrated MD2 modem
Order no.
Description
6NH7700-2AR60
Connecting cable with 2 x RJ-12 Western plugs for
connection to an MD1 or MD2 modem (RJ-12) with an
LTOP overvoltage protection module (RJ-12). The cable
is also suitable for an MD2 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!
Connecting the TIM 32 with the LTOP and dedicated line
The following figures illustrate the various options for connecting a TIM 32 (and all other TIM
variants with integrated MD2 modems) to the dedicated line over an LTOP using the
specified standard connecting cable.
For more detailed information on connecting, wiring up and setting the LTOP, refer to the
section
This allows the following end point and tapping point configurations.
