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 9261 T1 NAM also provides an
additional T1 network interface connector. Typical applications include:
HWide Area Networks (WANs)
HChannel extension
HVideo teleconferencing

Installing the I/O Card
The NAM’s I/O card provides the COM port, network, 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.

Installing the T1 NAM
!WARNING:
Do NOT remove any jumpers located on the battery. To do so can cause
non-volatile memory loss. Should a jumper become separated from the
battery, contact your service representative immediately.
!HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive
components from damage due to electrostatic
discharge (ESD) during normal operation. When
performing installation procedures, however,
take proper static control precautions to prevent
damage to equipment. If you are not sure of the
proper static control precautions, contact your
nearest sales or service representative.
The NAM is always installed in Slot 01.
CAUTION:
Be sure that you install the NAM in the correct slot so that it mates with its
matching I/O card. Otherwise, you could damage your card.
1. Remove the housing’s bezel, if applicable. See the housing installation instructions
for information.
2. Remove the NAM from the shipping box. Handle only by the top and bottom edges
to avoid damaging the card.
3. At the front of the housing, align the NAM with the upper and lower tracks of
Slot 01.
