What Does a T1 NAM Do?
The T1 NAM acts as an interface between the T1 digital network and the customer
premises equipment, converting signals received from the DTE to bipolar signals that
can be transmitted over T1 and Fractional T1 lines. The T1 NAM also provides a
DSX-1 drop and insert port to allow DTEs supporting the DS1 signal format to share
the network T1 with other high-speed equipment, as well as two synchronous data
ports. Typical applications include:
Wide Area Networks (WANs)
Channel extension
Video teleconferencing

Tools Required
A small Phillips screwdriver (#1 or #2) to install the T1 NAM
A small, flat-blade screwdriver to install the:
— I/O card
— Cable connections
Installing the I/O Card
The NAM’s I/O card provides the COM port, network, DSX and
DTE connections. The I/O card inserts directly behind the NAM
that it supports. Slot numbers are identical (in this case, Slot 01)
to facilitate correct installation.
1. Remove the I/O card from the shipping box. Handle only
by the top and bottom edges to avoid damaging the card.
2. At the rear of the housing, align the I/O card with the
upper and lower tracks of the slot. Push gently towards
the midplane until it stops and you cannot push the card
any further.
