HANDLING PRECAUTIONS FOR ST ATIC-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.

Available Options

The following options are separately orderable:
RJ48C modular cable for network access (20 ft.)
RJ48H T1 mass termination cable (5 ft.) for connecting seven T1 NAMs to an M66 block

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.

Connecting to the Network

1. Insert the 8-pin connector on the RJ48C network cable into the NET interface.
2. Insert the other end of the cable into the RJ48C modular jack.

Connecting to a DTE

If the DTE cable type is V.35, RS449, or V.11/X.21 (separately orderable):
1. Connect the plug to the
V.35, RS449, or V.11/X.21 end of the adapter cable (as appropriate).
2. Connect the EIA 530A end of the adapter cable to PORT 1 or PORT 2.
If the DTE cable type is EIA-530A:
1. Connect the EIA-530A

Installing the T1 NAM

In both the 2- and the 5-slot housings, the NAM is always installed in Slot 01. The NAM can be installed in any slot in the access carrier.
!
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.
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 the appropriate slot.

Troubleshooting

t e ous g
d
Symptom Possible Cause Solutions
No power, or none of the system LEDs are lit.
Power-Up Self-Test fails. Only Alarm LED is on after power-up.
Cannot access the NAM or the user interface.
For DC power source, DC power is not present.
For AC power source, the wall receptacle has no power, or the housing’ s power cord is not securely plugged into the wall receptacle or the back of the housing.
LED is burned out.
The NAM has detected an internal hardware failure.
Login or password is incorrect, COM port is misconfigured, or the NAM otherwise configured so it prevents access.
Check the DC power source.
1. Check the wall receptacle power by plugging in some equipment that is known to be working.
2. Check that the power cord is securely attache at both ends.
3. Check the circuit breaker.
Run the Lamp Test. If the LED in question does not flash with the other LEDs, then contact your service representative.
1. Reset the NAM and try again (see the Technical Reference).
2. Contact your service representative.
1. Reset the NAM (see the Technical Reference).
2. Contact your service representative.
Device Fail appears on the System Health and Status screen.
Not receiving data at DTE or DSX-1 interface.
The NAM detects an internal hardware failure.
Not cross-connected to the correct timeslot(s).
Record the 8-digit code from the System Health and Status screen, then contact your service representative.
