Dual PRI Installation
(Large/CS1000M)

NT5D97 - Dual PRI Card

The following applies to EUROPEAN EURO-ISDN PRI's.
- For Small/CS1000E (IPMG systems), see PRI programming.
- Universal Digital Trunk (UDT) card, see UDT E1 PRI Example.

Hardware:

The following resides in the Core/Network module:

Always use the ENB/DIS switch when inserting/removing cards.

Cables:

NTC03 - Clock Cable

Note, the NTCG03 comprises a 9-pin adapter, with a 2-pair RJ11 line cord (rollover):

External connectors:

Dip Switch Settings:

MSDL Settings: Choose a Port, all DCE to ON, all DTE to OFF (Use 422-A DCE)

DDP2 Settings: If using a Dual D-Channel daughter Board (NTBK51), you must set the MSDL device address.

Trunk 0: S12_1- OFF-120 ohms (ON-75 ohms is used if using coax cable)
S12_2- Spare
S12_3- Spare
S12_4- ON for PRI2/Off for DTI2
 
Trunk 1: S7_1- OFF-120 ohms (ON-75 ohms is used if using coax cable)
S7_2- Spare
S7_3- Spare
S7_4- ON for PRI2/Off for DTI2

Refer to the Circuit Card Reference NTP for full details.

NTCK45:

The NTCK45AA a cable is for systems equipped with an I/O filter panel, it connects the DDP2 faceplate J5 TRK port (P1, D-type 9 pin male) to the I/O filter (P2, P3 D-type 9 pin males), breaking out the two DDP2 trunks into two 9 pin D connectors.

Trunk Pinouts:

Use the following table when hooking up, be prepared to swap RX and TX pairs!

DB-9 (E1) (NT8D7217E6)DB-15 (T1)CSU/DSU * (RJ48/RJ45) (T-568B)
2 - Black/Transmit1 - White/Transmit1 - Transmit (R1) white/orange
3 - Red/Transmit9 - Black/Transmit (could be 8)2 - Transmit (T1) orange/white
6 - Black/Receive3 - Red/Receive4 - Receive (R) blue/white
7 - White/Receive11 - Black/Receive (could be Yellow)5 - Receive (T) white/blue

* DSU/CSU = Data Service Unit/Channel Service Unit, eg, the PTT modem.

Pinning a RJ45 to DB-9F Adapter:

Use the following adapter configuration with an E1, DB-9 end on the PBX (to NTCK45AA on J5).
You may need to reverse the TX / RX pairs - or swap orange & blue with T-568B (568A or 568B).

Note: Most RJ45 to DB-9F Adapters use this colour
scheme, but yours may not! Always check it first!

Loopback Adaptors:

  • DB-9 (E1) - Loop pin 2 to pin 6, and pin 3 to pin 7
  • DB-15 (T1) - Loop pin 1 to pin 3, and pin 9 to pin 11
  • RJ45 (DSU) - Loop pin 1 to pin 4, and pin 2 to pin 5

Note: An RJ45 connector will fit an RJ48 jack, but the key on an
RJ48 connector will prevent it from plugging into an RJ45 jack.

Remember, the D channel will not establish on a loop test.

PBX Programming:

Step 1. CEQU

LD 17

PromptResponseDescription
REQ CHG
TYPE CEQU
PRI2 X New PRI Loop number = slot/position of NT5D97 card in network shelf

Step 2. Build D- Channel

LD 17

PromptResponseDescription
REG CHG
TYPE ADAN
ADAN NEW DCH # Available D Channel Number
CTYP MSDL
DNUM X (0-15) Physical MSDL card address. All ports on the MSDL card share the same DNUM.
PORT X (0-3) Physical PORT number on MSDL card
DES Description: used to identify the link, can be up to 16 alphanumeric characters
USR PRI
IFC EURO Try EURO first- APAC may work in Asia
CNTY ETSI Country, ETSI = ETS 300: 102 basic protocol
CLID OPT1 OPT1 is the default for all EuroISDN interfaces
DCHL X PRI Loop Number
SIDE USR Prompted only if IFC = SL-1, ESIG or ISIG; one side is USR, the other NET
RLS 25 If not connecting to a Nortel CO switch-enter through
RCAP COLP Default for value for EUROISDN

INC (NO)/YES YES only if using Incoming Digit Conversion
CDR YES Yes for CDR records on this route
INC YES
LAST YES
OAL YES
AIA YES
MUS YES Yes if Music Route is available
MRT 21 Music Route Number

Step 4. Build Trunks

PromptResponseDescription
REQ NEW 30 Build all 30 channels at once
TYPE DID
TN X 1 PRI Loop and Channel
DES aaa..a Designator, eg, PRI1
CUST 0
TRK PRI2
PCML A Note: A for EURO-ISDN / MU for US, and switch to switch
NCOS
ROUT X 1 Route number and first member
CLS DTN Don't forget tone dialing!

Step 5. LPTI (Loop Timers)

Set CRC on/off. If you get Frame-slip errors, try changing this.

LD 73

PromptResponseDescription
REQ CHG
TYPE: PRI2
FEAT LPTI Loop number of PRI card location or CEQU PRI2 defined loop
LOOP L Loop
MFF CRC Usually CRC, or maybe AFF - must match provider

Step 6. SYTI (Clocking)

LD 73

PromptResponseDescription
REQ CHG
TYPE PRI2
FEAT SYTI
CCO
PREF L Loop for CC0 primary clock reference
SREF L Loop for CC0 secondary (alternative) clock reference
CC1
PREF L Loop for CC1 primary clock reference
SREF L Loop for CC1 secondary (alternative) clock reference

Step 7. CLID

(NET_DATA)

LD 15

PromptResponseDescription
REQ CHG
TYPE NET NET_DATA
CUST 0
ISDN YES
ENTRY 0
HLCL xx...x Digits to be inserted before DN on CLID
DIDN (YES)/NO Set to NO so DN is not sent out/ Set to Yes so DN is sent out

Note: LDN0 must be defined (LD 15) for ISDN PRI DID service. The length of LDN0 determines the number of trailing digits translated as the dialed DN on PRI DID routes.

Step 8. Clock Tracking

LD 60

.TRCK PCK = Primary clock / SCLK = Secondary clock / FRUN = Freerun

Step 9. PRI Startup

The MSDL / DCH will need a forced download (FDL) the first time its brought into service.
