Options for "Long Distance T1" (LD-T1)

Hello, does Cisco offer a VWIC that accepts and is configurable for LD-T1?

The provider says that "DNIS" needs to be set in the PBX.

I can provide more specs if needed, please ask.  Paul

Re: Options for "Long Distance T1" (LD-T1)

Yes, it does support what you are asking.  Any T1/E1 VWIC that comes with the UC500 supports both CAS and CCS T1's.  The CCS T1 (PRI) has a separate channel which is used for signaling and the "DNIS" digits you are reffering to are sent over that D channel to the UC500.

DNIS digits are the numbers that someone dialed to reach your company.  Since the phone company is sending you those digits, you can route calls in your company according to what the person on the far end dialed.  With POTS lines, the physical line is associated with the number.  Since a PRI is one physical line, the phone company as a service gives you the option to digitally (D Channel) see what number someone dialed to reach you.

When you have 20+ numbers (718) EEE - XXXX. The "EEE"s (Exchange code) usually stays the same and the XXXX's (Subscriber number) can differ.  When the phone company asks you how many DNIS digits to send, people usually say four because the exchange is always the same.  If exchange is different you can ask them to send five or more digits instead of four.  Five or more isn't always the necessary because the last four don't always overlap.

With CCA, you have the option under the direct inward dial tab to route calls based on that four digit number.

Hi Paul,

What on earth is Long Distance T1 LOL...

The UC supports a VWIC T1/E1 card, but not sure about the whole LD thing as I have never heard of this before (Must be a USA thing).

Can you elaborate a little further on this?

Cheers,

David.

Re: Options for "Long Distance T1" (LD-T1)

Marcus, we are now having an issue showing Caller ID on inbound calls.  The Voice provider is saying this:

"the Real Time Ani was not activated because the vendor didn’t have *ANI*DNIS* programmed on the PBX and the test calls were failing to a fast busy once the change was made"

Here is the current config of the Port:

controller T1 0/2/0

framing SF

linecode ami

ds0-group 0 timeslots 1-24 type e&m-wink-start

cas-custom 0

  trunk-group LDT1 64

Do you have any suggestions?

Thank you, Paul
