Direct Inward Dialing (Did) - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Description
Direct Inward Dialing (DID) lets outside callers directly dial system extensions. DID saves time for callers
who know the extension number they wish to reach. To place a DID call, the outside caller dials the local
exchange (NNX) and additional digits to ring the telephone system extension. For example, DID number
9264 3111 can directly dial extension 111. The caller does not have to rely on attendant or secretary call
screening to complete the call.
Direct Inward Dialing requires DID service from Telco.
In addition to direct dialing of system extensions, DID provides:
DID Dialed Number Translation
Flexible DID Service Compatibility
DID Intercept
DID Camp-On
There are 20 DID Translation tables that can be divided between 2000 entries.
DID Dialed Number Translation
DID allows different tables for DID number translation. This gives you more flexibility when buying DID
service from Telco. If you cannot buy the exact block of numbers you need (e.g., 301~556), use the
translation tables to convert the digits received. For example, a translation table could convert digits
501~756 to extension numbers 301~556.
The UNIVERGE SV8100 system has 2000 DID Translation Table entries that you can allocate among the
20 DID Translation Tables. One translation is made in each entry. For a simple installation, you can put all
2000 entries in the same table. For more flexibility, you can optionally distribute the 2000 entries among
the 20 tables.
In addition to number conversion, each DID Translation Table entry can have a name assigned to it.
When the DID call rings the destination extension, the programmed name is supplied.
Flexible DID Service Compatibility
With three-digit service, the Telco sends three digits to the system for translation. Be sure to program
your system for compatibility with the provided Telco service. For example, if the Telco sends four digits,
make sure you set up the translation tables to accept four digits.
The system is compatible with Dial Pulse (DP) and DTMF DID signaling. DID trunks can be either wink
start, immediate start, 2nd Dial or Delay.
