Installing and Cabling the TN1654 Circuit
Pack (T1 only)
The TN1654 circuit pack are normally installed in the Switch Node Carrier on the central port network
(PN), which is in an MCC1 media gateway. However, if you have more than 2 remote PNs or you are
installing the circuit pack in the remote PN, then you install them in a port carrier in the media gateway.
The remote PNs can be SCC1 media gateways.
The installation instructions are provided as examples only.
Installing the circuit pack(s) in a Switch Node Carrier
You can install up to 2 TN1654 circuit packs in a Switch Node Carrier. If you need to install more than 2,
install them in a port carrier.
1
Install the TN1654 circuit pack in either slot 1 or 21 of the Switch Node Carrier close to a
TN573B SNI circuit pack.
2
On the backplane, connect a 14-inch (36 centimeter) Y cable from the TN1654 circuit pack to the
TN573B circuit pack. For a connectivity diagram see
page 53.
3
Connect an H600-348 Quad cable to the other side of the Y cable.
If you go through a T1 line and out through the public network to a remote PN, FCC rules require that
you install a Channel Service Unit (CSU). Go to
52
NOTE:
Be sure to label all of the cables as they are installed.
CAUTION:
When adding or replacing any hardware and associated cables and adapters, be sure to
ground yourself against electrostatic discharge (ESD) by wearing a grounded wrist strap.
CAUTION:
Install the TN1654 circuit pack in either slot 1 or slot 21. Installing it in any other slots can
damage the circuit pack and the media gateway. Do not do it.
NOTE:
The Y cable used with the TN1654 circuit pack is different than the Y cable used with the
old TN574 DS1 converter circuit pack. These cables are NOT interchangeable.
