ICC I/O Module Network Pinouts

The first pinout below lists the network pinouts for the RJ45 Jack/Receptacle (female) on the ICC I/O Module. Use this table as a reference when wiring together an RJ45 connector (male) to a cable that you will then insert into the RJ45 Jack/Receptacle on the ICC I/O module. This covers both T1 and E1 issues.

VCO side	        Network side
----------	        --------------
Pin 1 Tx Ring  -    network Rx Ring
Pin 8 TX Tip   -    network Rx Tip
Pin 4 Rx Ring  -    network TX Ring
Pin 5 Rx Tip   -    network TX Tip

Also, a VCO/4K to Cisco AS5300 cable pinout would look like this:

VCO side	       AS5300
----------	       ----------
Pin 1 TX Ring  -   Pin 1 Rx Ring
Pin 8 TX Tip   -   Pin 2 Rx Tip
Pin 4 Rx Ring  -   Pin 4 TX Ring
Pin 5 Rx Tip   -   Pin 5 TX Tip

Note the orientation of the RJ45 Jack/Receptacle on the ICC I/O module. When viewing the RJ45 Jack/Receptacle on the ICC I/O module, you will see the 'key/notch' of the jack on your left-hand side. Given this viewing orientation, Pin 8 is on the top and Pin 1 is on the bottom.

The above descriptions are repeated for the following VCO I/O-Modules and SDS MDF-adapters:

  • The [120 ohm, (non-coax)] RJ45/DB15 VCO I/O Module for the 4xT1 and 4xE1-120 ohm cards. (This RJ45 jack has the same orientation as the ICC I/O Module's RJ45 jack.)

  • The [120 ohm, (non-coax)] RJ45 SDS MDF Adapter for the 4xT1 and 4xE1-120ohm cards.

    Note: For this MDF adapter, when viewing the RJ45 Jack/Receptacle on the MDF adapter, you will see the 'key' of the jack on your right-hand side. Given this viewing orientation, Pin 1 is on the top and Pin 8 is on the bottom.

  • The [120 ohm, (non-coax)] RJ45/DB15 VCO I/O Module for the PRI/N and E1-PRI-120 ohm (NET5)cards. (This RJ45 jack has the same orientation as the ICC I/O Module's RJ45 Jack.)

  • The [120 ohm, (non-coax)] RJ45/DB15 SDS MDF Adapter for the PRI/N and E1-PRI-120ohm (NET5) cards.

    Note: For this MDF adapter, when viewing the RJ45 Jack/Receptacle on the MDF adapter module, you will see the 'key' of the jack on top. Given this viewing orientation, Pin 1 is on the left and Pin 8 is on the right.
