“Remote Access” on page 8 provides details about setting up and using remote access in private networks. The scenarios in Chapter 2 provide examples of remote access setup and use in private networks. In addition, Chapter 4, “Security,” provides information about how remote access is used in private networks.
Remote access allows tandem and UDP calls and non-local private network ARS users to call out on local trunks connected to the PSTN, permitting cost savings. Default COR permissions and restrictions must be assigned to all tie or all non-tie trunks, depending on whether private network trunks are tie trunks (analog, T1- emulated tie) or non-tie (PRI) facilities. Toll and outward restrictions should be removed from the COR for these facilities. When a tandem UDP or ARS call is routed across the private network on tandem trunks, the local COR FRL at the receiving system is compared to the FRL for the local ARS or UDP route. For the call to go through, the default COR FRL must be equal to or greater than the route FRL. UDP and ARS at a remote system can route calls to yet another system on the private network.
A Remote Access code can be programmed into the non-local dial plan to allow toll savings for remote access calls across the private network. Barrier codes and associated barrier code Disallowed Lists and FRLs should be applied.
A caller can also reach remote access on a networked system by calling in on DID or dial-plan routed trunks or by calling in on a line/trunk programmed for shared or dedicated remote access. During Night Service operation, a user can call into a trunk programmed for shared remote access and use remote access to reach non-local extensions. As in non-network operation, the local system applies any required restrictions. Barrier codes and other remote access restrictions should be assigned for this type of calling.
