DID Applications
When using DID or DNIS, 3Com recommends ordering telephone
numbers that easily fit into the NBX 100 numbering plan. Although the
numbering plan is extremely flexible, it is far easier to use have 3 or 4
digit DID\DNIS codes. This allows for a simple dial plan implementation.
If the client is using 3-digit internal extensions, try to use the 100-499
range.
Have the client ask the carrier to use the corresponding three
digits for the DID\DNIS numbers/code. If the client is using 4-digit
extensions, have them ask for the 1000-4999 range and that the carrier
to use the corresponding four digits for the DID/DNIS numbers/code.
If the client requires Caller-ID type services, the carrier
must support
in-band ANI. The client will need to inquire as to the availability of this
support as part of the order process.
CSU
An external CSU is required with each T1 installation. Many CSUs support
conversion of ESF/ B8ZS services into D4/AMI. In some locations it may be
easier to order the T1 as ESF/B8ZS and perform the conversion in the
CSU. If the client chooses this method, BE SURE that the CSU supports
this conversion.
