Does Cisco VWIC2-1MFT-1T1/E1 support Primary-ni2?

Hi,

Our customer tries to connect to a local service provider who provides ISDN PRI (voice) service not for a long time.

The provider can only support ISDN switch type primary-NI2. While our customer has Cisco 2851 voice gateway with VWIC2-1MFT-1T1/E1 installed, and there is no option of Primary-NI2 switch-type.

Does this voice card support Primary-ni2?

Thanks

JJ

Hi,

I think NI2 only adds features like IE calling name display.

NI1 should work fine for basic services.

I meant, ...configuring NI1 on the router ... should work fine.

Re: Does Cisco VWIC2-1MFT-1T1/E1 support Primary-ni2?

The router shows the command for isdn switch-type as primary-ni. This usually works very well with Primary-ni2 switches. I have had a few colleagues tell me a while back, that primary-ni1 switches some times dont work very well when your router is configured to use primary-ni setting. Either ways you are limited to setting your switch type on your router as primary-ni regardless of what the telco uses (ni1 or ni2).

Re: Does Cisco VWIC2-1MFT-1T1/E1 support Primary-ni2?

Hi,

The following is the debug isdn q931 information when tried to dial-out from IP Phone(CCM 5.0 with Cisco 2851 VGW), configured ISDN Switch-type primary-ni.

I also was wondering for the same call why it showes three times of the same information while from the working customer, the information will only displayed once.

In the meanwhile, from the debug, it tells us something T303 timeout.

The service provider always tells us that on their side, looks everything okay.

Can have anyone provide suggestion?

Thanks,

JJ

Re: Does Cisco VWIC2-1MFT-1T1/E1 support Primary-ni2?

Hi JJ,

you see the call three times because apparantly the switch is not responding, so the router retransmits the message. Before we point to the switch, would you please:

- let us know if this circuit works for some or no calls.

- verify or send here, "show controller", "show interface", and "show isdn status", the latter taken before and after attempting a call.

- IOS version and configuration. Non relevant info can be purged.

- double check cabling and circuit, eg NO cat 5 cable is used (only specific telco), etc.

Re: Does Cisco VWIC2-1MFT-1T1/E1 support Primary-ni2?

Hi,

I attached the information your requested.

-- No any phone call can go out via PRI

-- Show controller information is clearn

Show interface (D channel interface) has the CRC increased all the time

--- Show isdn status most of the time, does not change. But maybe sometimes it is not stable(Layer 2)

Thanks

Finally the provider reconfigured their side and find some parameters are wrong on their side.

Now it works fine.

Thanks

I use that card all the time and they do support NI-2. Another post is right they only for things like calling name etc..

If the other end of the pri does not match or the clocking is gone ou will see an unstable pri.
