CS1K to Cisco VG204XM

[KCFLHRC]

Has anyone successfully connected the CS1K via a Universal Trunk Card to a Cisco VG204XM using ground start? If so what settings in each device are you using? Should be simple enough but guess what, it doesn't work right.

I don't think the card is used that much in the UK, but I did find some stuff. It doesn't look as if it supports ground start.

There were some records found and the second one points to some error in the documentation.

The UDT card in default mode supports PRI working. If DASS or DPNSS is required some modifcations have to be made in the card CLI.

Default modes - supports normal E1 (2MB) and T1 (1.5MB) configurations for applications such as EuroISDN
E1- Usage = PRI2, CRC4 = NO
T1- Usage = PRI, Frame Mode = ESF, Line Code = B8ZS, Yellow Alarm = FDL, LBO = 0-133 FT

Non-default - supports DTI2, DPNSS and DASS.

E1 / T1 selection is achived by use of DIP switch 1 on the card: ON - E1, OFF - T1

If using DTI2 or DPNSS or DASS, modifications to the card default settings are required. This is achieved using the CLI via the RS232 port (9600 8 none 1)

CS1000E NTDW79 Universal Digital Trunk Card

When the UDT card was introduced in 2010, the style of carrier cable connection was harmonized globally to the RJ48C Ethernet style cable. This replaced various cable variations (NTBK04xx / NTBK05xx) based on COAX, 9 pin, & 15 pin DSUB connectors.
The RJ48C carrier cabling approach is also consistent with the CS1000M DDP/DDP2 packs (NT5D12 / NT5D97) as well as the CS1000E PRI Gateway Chassis (NTDW77).

To break out of the CS1000E system, there is an adaptor (NTBK65AAE5) that connects the RJ48C connection to the 50 pin MDF connector on the cabinet or chassis. The adaptor is kitted with the NTDW79 pack when purchased. It can also be ordered from Avaya separately as merchandise.

The correct cable to use is a Shielded cat5/cat5e Ethernet style cable. The more commonly available un-shielded Ethernet cable will work, but is more susceptible to signal degradation so should not be used. Avaya does not provide this cable as length and building wiring preference must be determined by the installer.

The following table has the signal pin out of the NTBK65 adaptor. Note that the Transmit/Receive direction is with respect to the UDT card. For example pins 4 & 5 TX is UDT output.

50 Pin MDF RJ48C Signal Name
24 1 RX RING
49 2 RX TIP
3 n/c
23 4 TX RING
48 5 TX TIP
6 n/c
7 n/c
8 n/c

Note that the pin out was INCORRECT in the originally published NTP document NN43001-30 - ISDN Primary Rate Interface Installation and Commissioning (Pg 112). It has subsequently been corrected in an updated version as of Dec 2011


**** Note that the pin-out of the 50 pin MDF connector on the CS1000E and Option 11 chassis has not changed for the UDT pack and is still compatible with previous carrier wiring techniques. If an existing E1/T1 card (NTAK09 / NTAK10 / NTAK79 / NTBK50 / NTRB21) is being replaced in a system with a NTDW79 UDT pack, the existing Avaya/Nortel supplied twisted pair cables (NTBK04 / NTBK05) should still be sufficient and do not need to be swapped out.

The Cisco end does have the option of loop or ground start. We have it set up for ground start on both ends. Connected to an NT8D14 EXUT card. I can pull dial tone but dialing on the trunk is intermittent. Works fine from an analog phone sending DTMF but from a digital set the DTMF is sporatic.

 

[hawks]

Do you get the same results on Loop Start? Also how about calling from the Cisco to the CSK1 are there any DTMF issues?

 

[KCFLHRC]

I'll try to explain this the best I can because it's really strange. The Cisco is providing the ground start trunk. I dial the ACOD from the CS1K and pull dial tone every time. If I'm on an analog set I can send DTMF just fine, I know, the dial pad is live always on an analog, I get that. Now the weird part. If I dial the ACOD from the digital phone, I hit the dial pad and hear no DTMF on my test set that is bridged onto the trunk in monitor mode, however, if I dial the ACOD from the digital set, get dial tone, then come off hook on my test set that is bridged onto the trunk, guess what, I can send DTMF. Almost like the CS1K is not sensing that it really pulled dial tone, but coming off hook with the test set some how completes the circuit. Very strange indeed. I'm thinking maybe an impedance or voltage issue out of the Cisco. I have not tried loop start yet but that is an option.

 

[hawks]

Or you terminated on the 600 or 900 ohm pair of the card?

 

[KCFLHRC]

The impedance is software on this card, correct?

 

[Firebird Scrambler]

On the good old Norstar systems, you could activate DTMF on pulse lines by pressing * or #. Not sure which one it was. Could the same apply to CS1K digital sets?.

Yes it's via software but the card has to BA or higher. Also have tried the # like firbeird was talking about for whatever strang reason I've seen that work also.

 

[KCFLHRC]

# doesn't work either, But keep in mind what I said. If I come off hook on my buttset after the ACOD I can dial from the digital set. Card is a BB

 

[hawks]

Does seem strange, can you try.
Dial access code with digital set (I understand it should not work at this point)
Don't hang up but instead take a Ground wire if close enough and Ground the circuit real quick and see if you can dial through now.

 

[hawks]

Also make sure DTMF is on in LD 15
