Caller ID	3

For 6.1 and later systems, Caller ID and Automatic Number Identification (ANI) information is conveyed across the private network when PRI tandem trunks are used to route the call and under the following conditions:

■The call is transferred using a DSS with one-touch transfer with automatic completion.

■The call is received on a PSTN trunk assigned to ring directly into a calling group with a non-local member.

■The call is received on a Personal Line and the principal user has activated Forward to a non-local extension and the Forward Delay option is set to one ring.

■The call is transferred to a user that has activated Forward to a non-local extension and the Forward Delay option is set to one ring.

For Release 6.0 systems, Remote Call Forwarding can be used in combination with Caller ID on a loop-start PSTN line connected to a networked system’s 800 LS-ID line/trunk module (loop-start ID delay must be on). To pass Caller ID information across the network when a call is transferred, set the Remote Call Forwarding Delay to one ring. Transfer of the call must be completed before the call is forwarded.

For 6.0 and later systems, Caller ID and ANI information is not conveyed across the private network under the following conditions:

■The call is routed over T-1-emulated tie trunks or analog (E&M) tie trunks.

■A call is manually transferred by a user or is transferred by an automated attendant.

Calling Restrictions 3

Outward restrictions, toll restrictions, Allowed/Disallowed Lists, Night Service restrictions, Extended Station Status restrictions, and the prohibition of trunk-to- trunk transfers do not apply to calls made to extensions in the non-local dial plan. These restrictions are still active for other calls.

To prevent toll fraud, dial-access to pools must not be permitted for pools of private network trunks.

!CAUTION:

Unless networked systems are co-located, each system should have at least one loop-start line connected to the PSTN. The line is required to allow connection of a power-failure telephone to the Power-Failure Transfer (PFT) jack on a module as a power outage backup and for correct routing of emergency and other N11 calls. To ensure that the correct services are reached, if the loop-start line is used for emergency or other N11 calls, it
