IRQ Level

The  AT/SD, AT/SDD, and AT/SS may use IRQ

2(or 9),10,11,12,or 15.

IRQ 10 is default.

Selection is made by a single jumper.

AT/SD and AT/SDD jumpers are labelled :

IRQ

15 12 11 10	IRQ2

AT/SS jumpers are labelled:

IRQ

15  11  9

    12 10

DMA Channel

The  AT/SD, AT/SDD, and AT/SS may use DMA Channel

0,1,3,5,6,or 7.

DMA Channel 6 is default.

Selection is made by a pair of  jumpers, one for the request, the

 other for the acknowledge.

AT/SD and AT/SDD jumpers are labelled :

DACK   7  6  5  0	DACK   3  1

   DRQ   7..6..5..0	   DRQ   3  1

AT/SS jumpers are labelled:

Port Address
I/O PortAddress

I/O  Port Address is controlled by switches 1,2, and 3.

On the AT/SD and AT/SDD switches 5 and 7 should be OFF (away from the board)

and switches 4,6, and 8 should be ON (toward the board).

On the AT/SS  switch 4 should be ON (toward the board) and there are no

switches 5,6,7, or 8.

(On is toward board)

Switch	Base I/O

1	2	3	 Address in Hex

On	On	On	280 (Default)

On	On	Off	290

On	Off	On 	2E0

On	Off	Off	2F0 *

Off	On	On 	300

Off	On	Off	350

Off	Off	On 	380

*2F0 conflicts with COM2

Clock Rate

 A  "0" Clock Rate is used to specify external clocking(from the DCEor DSU). This is the default.

Other clock rates (given in kilobits per second) may be chosen between 56 (56 Kilobits/sec)and 2500 (2.5 Megabits per second. These other rates are internally generated and are generallyonly used for back-to-back  bench demonstrations and development.

Port1 Line Type

Line types of "Dial", "Leased", and "Disabled" are supported.

Port2 Line Type

Currently this is forced to "Disabled".

Leased Line

LEASED 56   ADTRAN DSU III AR

Clocking is the first thing to check with all leased digital lines. Usually for long distance leased lines both units derive their clock from the network:

ADTRAN MENU: 3 CONFIG/1LOCAL/1NETWORK OPT/5CLOCK SOURCE

=2FROM NETWORK.

Many installations have worked better with one DSU set to provide the network clock.

     ADTRAN MENU: 3CONFIG/1LOCAL/1NETWORK OPT/5CLOCK SOURCE

=1MASTER

   Other normal settings are:

 Synchronous,

 V.35,

 Dialing disabled

 CS Forced ON

 CD Normal

 Network type DDS.

             NOTE:  (Do not use RS232 & V.35 cables simultaneously--"TR gets stuck ON".)

LEASED T1   ADTRAN TSU

Clocking is the first thing to check with all leased digital lines. Usually for long distance leased lines both units derive their clock from the network:

ADTRAN MENU: 3 CONFIG/1LOCAL/1NETWORK OPT/5CLOCK SOURCE

=2FROM NETWORK.

Switched 56

SWITCHED 56   ADTRAN DSU III AR

DO NOT USE "CRNT" in dial string for Adtran DSU IIIARjust use "CRN" followed by the number to be called.  For example, 'CRN4447765' will dial 444-7765.  "Quick setup" does not set dialing to V.25 HDLC.  Follow this setup.

ADTRAN DSU III AR set up for switched 56 operation:

3CONFIG/1LOCAL/1NETWORK/...

1LOOP RATE/7=56K

4NETWORK TYPE=Select the Network you have

(AT&T/MCI SW56 or US Sprint SW56)

5CLOCK SOURCE=2FROM NETWORK

3CONFIG/1LOCAL/2DTE OPTIONS/...

1RATE=1DTE56K

2CONNECTOR=2V.35

3DATAFORMAT/2SYNCHRONOUS

4DTE CMD OPTION=3V.25 SYNC

5TRANSMIT CLOCK=NORMAL

6CS=1FORCED ON

7ANTI-STREAM=1TIMER OFF

8CDOPTIONS=NORMAL

9TR OPTIONS=2IDLE WHEN OFF  (So we can hang up)

ASR OPTIONS=5OFF TEST + OOS

3CONFIG/1LOCAL/3TEST OPTIONS/...

3EIA LLB=1DISABLED...

4EIA RLB=1DISABLED...

3CONFIG/1LOCAL/4DIAL OPTIONS/...

2AUTO ANSWER/2ENABLED

After the DSU III AR is configured properly and NiwRAS and RAS are launched, the ADTRAN "RS", "CS", and "TD" lights should all be "on".  The display will read "IDLE, LOOP IS NORMAL".  If the display says "INCOMING CALL, LOOP IS NORMAL", this means the central office has your line configured as leased rather than dial.


Single ISDN BRI

SINGLE ISDN BRI   ADTRAN ISU 128

Quad ISDN BRI

QUAD ISDN BRI   ADTRAN ISU 512

DO NOT USE "CRNT" in dial string for ISDN, just use "CRN" followed by the number to be called.  For example, 'CRN4447765' will dial 444-7765.  "Quick setup" does not set dialing to V.25 HDLC.

The Adtran ISU 128 has two main versions out in the world:

old "L1" which has a set of V.35/530 switches on the rear.

Newer "L2,L3,L4,L5" which select V.35/530 from the menu.

Make sure that:

1. V.35 is selected (back on old, menu on new)

2. SR light is off when call is not up (DSR if call up on old DSR OFF Idle +Test on new)

3. DTR Idle when Off new only.

4. CD if call up on old, Normal on new.

5. Both LDNs are entered (possibly identical on AT&T) so can bond.

We recommend BONDING mode 1 , Call type Data56Kbps, Bit rate 112000.

After the ISU128 or ISU512 is configured properly and RAS is launched, the "RS", "CS", and "TR" lights should be "on" and the "TD" light should be flashing.  The ADTRAN display should read either "AT&T-5ESS READY", "DMS-100 READY", "ISDN-1 READY" or "NEC READY", depending on what type of switch you have.

At the end of the dial string with ISU128 software 5.03 or higher, "#3" indicates multiples of 56, "#4" indicates multiples of 64.  Use "#3" to call a Switched 56 line.

Dial strings for the ISU512 can be:

#3#0      Single 56

#3#7      7x56

#4#3      3x64

#4#8      8x64 = 512

ASCEND VSX-BRI single BRI or QUAD BRI versions

The Ascend VSX-BRI unit is generally similar to the Multiband in configuration. Ascend requires a different SPID for each channel (two SPID's per BRI).

 see	ISDN PRI and Dialing T1


ISDN PRI and Dialing T1

     Ascend or AT&T ABC

ASCEND or ABC(Acculink Bandwidth Controller) installations may generally benefit from using Niwot Cable P/N 0.1264 DB25S to HDB44P Ascend V.35.

Multiband Plus or VSX T1

ASCEND MULTIBAND PLUS or VSX CONFIGURATION NOTES:

Host/Quad Port Directory Call Mgm='Static' or 'Manual' worked OK,  'Dynamic' and 'Delta' did not.

Port configurations Clear=DTR Inactive, Dial=V.25 bis, and Answer=DTR Active.

In order to call an ADTRAN ISU 128, Bonding mode 1 ,  data Svc of 56, and Base Ch Count of 2 are recommended.  One way to do this is to store the desired number and specify bonding mode 1 within the Ascend/ABC Directory and using CRSx where x is the directory entry number to be used for dialing.

Following are examples of two Ascend dial strings:

ASCEND Call Profile	CRS02	Used by users of an ABC IMUX who generally run AIM bonding, but want to call an ISDN line and specify Bonding Mode 1, the telephone number, Bonding Mode 1, 56K channnels, and 2 channels are all specified in "Call Profile 2)

ASCEND 56	CRN17007375813;SCTN56;BWR20;NMC

This string illustrates the extensions to V.25 bis in the ABC/Ascend, specifies that the calls are multiple Switched 56, that 20 calls are to be made in parallel, and No Management Channel is desired. The destination for this call is an ABC test IMUX accessible from the AT&T long distance network.
