CANADIAN EQUIPMENT LIMITATIO NS  
Notice: The Canadian Industry and Science Canada label identifies certified equip-  
ment. This certification means that the equipment meets certain telecommunications  
network protective, operational, and safety requirements. The Department does not  
guarantee the equipment will operate to the user’s satisfaction.  
Before installing this equipment, ensure that it is permissible to be connected to  
the facilities of the local telecommunications company. The equipment must also  
be installed using an acceptable method of connection. In some cases, the com-  
pany’s inside wiring associated with a single-line individual service may be  
extended by means of a certified connector assembly (telephone extension cord).  
Compliance with the above conditions may not prevent degradation of service in  
some situations.  
Repairs to certified equipment should be made by an authorized Canadian main-  
tenance facility designated by the supplier. Any repairs or alterations made by  
the user to this equipment, or equipment malfunctions, may give the telecommu-  
nications company cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connec-  
tions of the power utility, telephone lines, and internal metallic water pipe sys-  
tem, if present, are connected together. This precaution may be particularly  
important in rural areas.  
Users should not attempt to make such connections them-  
selves, but should contact the appropriate electric inspection  
authority, or an electrician, as appropriate.  
The Load Number (LN) assigned to each terminal device denotes the percentage  
of the total load to be connected to a telephone loop which is used by the device,  
to prevent overloading. The termination on a loop may consist of any combina-  
tion of devices subject only to the requirement that the total of the Load Numbers  
of all devices does not exceed 100.

1 .0 GEN ERAL  
1 .0 1 Un it O ve rvie w  
The ADTRAN NT1 Type 400 provides a basic rate interface be-  
tween the customers ISDN Terminal Equipment (TE) and the  
ISDN Network. Two interfaces are provided for this purpose: con-  
nection to the ISDN network is made by the “U” interface and  
connection to the customer's ISDN TE is made by the S/ T inter-  
face.  
The NT1 Type 400 is available in two configurations:  
• The NT1 Type 400 Standalone with an internal power supply,  
Part No. 1212.016L1.  
• The NT1 Type 400 Circuit Pack, Part No. 1212.010.  
The ADTRAN NT1 Type 400 Standalone consists of two parts, a  
metal housing containing the power supply, connectors, and the  
NT1 Type 400 Circuit Pack. The Circuit Pack can be removed from  
the housing by removing the plastic front panel and sliding the  
unit out of the housing. This allows access to the option switches  
which may be reset by the customer. The NT1 Type 400 Circuit  
Pack can also be purchased as a separate unit and mounted in a  
Type 400 NCTE rack, as indicated in APPENDIX A.  
LED In d ica to rs  
Table 1 describes the status of the LEDs located on the front panel  
of the NT1 Type 400. There is a READY and ERROR indicator for  
each port of the NT1 Type 400.

Hz flash rate (8 flashes per second) indicates a network problem.  
A slower 1 Hz rate (1 flash per second) indicates an S/ T interface  
problem.

Ba sic Ra te De scrip tio n  
ISDN Basic Rate Service consists of two “B” channels at 64 kbps  
and a single “D” channel at 16 kbps. Basic Rate Service (2B+D Ser-  
vice) provides a total of 144 kbps to the customer for the transport  
of voice, circuit switched data, and packet switched data. Each  
B” channel can be used for voice or data. The “D” channel carries  
the signaling information needed for call processing. The “D”  
channel can also carry packet switched data using the X.25 proto-  
col.

Pa ssive Bu s De scrip tio n  
The “S/ T’’ interface used to connect to the customer TE has the  
ability to connect multiple devices. This arrangement is referred  
to as the “passive bus” and can be used to connect up to eight TEs  
to the same Basic Rate line, as described in APPENDIX B.  
Po w e rin g TEs fro m th e N T1  
The ADTRAN NT1 Type 400 can be used to provide power for  
customer TEs. If the NT1 T400 circuit pack is used, a total of 12  
watts is available. If the NT1 Type 400 Standalone unit is used, a  
total of seven watts is available. This power can be provided by  
Power Source 1 (PS1), which provides power over the transmit  
and receive wire pairs used by the “S/ T” interface and requires no  
additional wire pairs; and by Power Source 2 (PS2), which pro-  
vides power over an additional wire pair.

Re a r Pa n e l  
The NT1 Type 400 Standalone rear panel contains three RJ45 con-  
nectors, as illustrated in Figure 1. A single connector, labeled  
“NETWORK,” is used to connect to the ISDN network. The re-  
maining two connectors, labeled “CUSTOMER 1” and “CUS-  
TOMER 2,” are used to interface to the customer’s TEs. These  
connectors are wired in parallel, and can be used to connect mul-  
tiple TEs in a passive bus arrangement.

To power-up the NT1 Type 400 Standalone for the first time, per-  
form the following procedures in order:  
1. Plug the power cord into a grounded, 120 VAC, 60 Hz recepta-  
cle.  
2. Verify that the ERROR indicators are illuminated. After about  
15 seconds, the READY indicators should flash at a 1 Hz rate.  
Should any of these indicators fail to operate as stated, see Sec-  
tion 3.0 Troubleshooting on page 5.

After successfully powering up the NT1 Type 400, the ERROR in-  
dicators should be on and the READY indicators should be flash-  
ing. Make sure that the TEs are properly terminated. Plug each TE  
into one of the S/ T connectors at the rear of the unit.  
After the TE powers up, the ERROR indicators should go out.  
There may be some delay between plugging in the TE and the ER-  
ROR indicators going out, depending on the specific TE in use. If  
the ERROR indicators fail to go out, see Section 3.0 Troubleshooting  
on page 5.  
When the ERROR indicators go out, the READY indicators should  
illuminate. The TE will now be ready to place and receive calls.  
There may be a slight delay between the appearance of the

RACK IN STALLATIO N  
The ADTRAN NT1 Type 400 Circuit Pack, Part No. 1212010, can be purchased as  
a separate unit for installation in a Type 400 NCTE rack. This configuration pro-  
vides a central location for the NT1 in a customer's wiring closet, and facilitates bat-  
tery backup. Refer to ADTRAN's Building a Battery Protected ISDN Phone System  
for a complete description of the centrally located battery back-up system.  
Figure A-1 shows the connector pin assignments of the ADTRAN NT1 Type 400  
Circuit Pack. The Type 400 rack supplies -48V to the Circuit Pack. In addition, the  
Type 400 rack provides access to the necessary wire pairs for connection to the  
network and the customer's TE.  
After ensuring that connections to the Type 400 rack are correct, and the circuit  
pack has been optioned properly, insert the circuit pack into the Type 400 rack by  
firmly pushing the circuit pack into one of the available slots. The circuit pack  
should slide in smoothly and snap into place.

S/ T BUS CO N FIGURATIO N S  
SHORT PASSIVE BUS  
The short passive bus configuration allows the connection of up to eight TEs at any  
point on the bus. The bus length is limited to 600 feet, as illustrated in Figure B-1.  
To select this bus configuration, set switch 1-2 to the Short position. The bus ter-  
mination resistors (TRs) can be placed at any point along the bus. If the TEs have  
internal TRs that can be optioned, only one TE's TRs should be enabled. The TRs  
in the NT1 Type 400 are enabled by setting switches 1-3 and 1-4 to the ON posi-  
tion, and switches 1-5 and 1-6 to the OFF position. If the unterminated TEs are  
placed within 20 feet of the NT1, set switches 1-3 and 1-4 to the OFF position, and  
switches 1-5 and 1-6 to the ON position. The switch settings should always be  
maintained, unless an external 100 ¾ resistor is being used. If an external TR is  
used, set switches 1-3 through 1-6 to the OFF position.

This bus configuration allows the connection of up to eight TEs at ranges up to  
3000 feet from the NT1 Type 400, as illustrated in Figure B-2.  
To select this mode, set switch 1-2 to the Long position. A TR must be centrally  
located to the TEs. The TRs in the NT1 Type 400 are enabled by setting switches  
1-3 and 1-4 to the ON position, and switches 1-5 and 1-6 to the OFF position.  
These switch settings should always be maintained, unless an external 100 ¾ re-
