INDIALING THROUGH MAIN-PRI
I-26 INDIALING THROUGH MAIN-PRI
1. General Description
With this feature a call destined for a satellite PBX via DID or Network Inward Dialing (NID) will automatically
be routed to the satellite station by the main PBX over a tie trunk.
2. Operating Procedure
1. A 4-digit number is received via DID or NID at a main PBX.
2. One or more sets of one thousand digits or more are designated for each satellite location. A main PBX
checks the digits and routes the call over a tie trunk to the appropriate satellite.
3. The other three digits are then transmitted to the satellite, where the call is switched to the proper station.
4. When a satellite PBX is assigned more than one thousand digits, each set of a thousand digits will refer to
a separate trunk group, while each trunk group will be assigned to a separate incoming switch.
5. When a PBX is used as a main PBX, the thousands of digits may be deleted or left intact when the dialed
digits are pulsed out to the satellite. All four digits may be transmitted to a satellite. A system may also
employ separate trunk groups for each thousand digits assigned to a satellite.
