Table 2–9, page 2-49 shows how the system manager sets up the systems so that users on each system can access the PSTN facilities connected to the other system. Routing details are summarized in Table 2–10, page 2-50. As you review these tables, keep the following points in mind:

SMDR is set up to record incoming and outgoing calls with Talk Time enabled, and MERLIN LEGEND Reporter supplies more refined and detailed information about the calling group calls on System C, where order-takers and customer service are located. The system manager must take time zone differences into account. For example, if an ARS call is routed over private trunks from System C to System D, System C’s SMDR report might show the outgoing call, at 2:00 p.m. local time, on a tandem tie trunk. The same call is reported on System D’s SMDR report at about 12:00 noon local time.

In this scenario, UDP routes are set for either voice or data but never both. Tandem T1 tie trunks do not allocate voice and high-speed data service dynamically. Because video and 2B data traffic is limited to a few extensions on each system, most T1 tandem tie channels are used for voice communications and set for Tie-PBX operation; data tie channels are programmed for data.

Security considerations are paramount because of the seasonal workers employed both at the headquarters office and the West coast office during busy sales and shipping periods (although West coast temporary shipping personnel have less access to telephones). Many extension FRLs are set to 0 and 1, the most restrictive values. As an extra safeguard, the remote access default COR FRL is set at 3 on both systems. This allows certain local ARS routes to be reserved for special purposes and prevents international calling via a non-local system. As in Scenario 1, barrier codes are required for non-network and intersystem remote access calls made by dialing a non-local Remote Access code.

The system manager and one technician use the Remote Access codes programmed into the non-local dial plan to program the other system on the private network. Therefore the UDP route is set to 6, and only a few users can access it. The manager and technician use all 11 characters of their barrier codes and change them two or three times a week.
