is connected to a Network Termination (NT1) device, which is physically located on the same premises as the system. The NT1 device connects to the Local Exchange that supports Numeris VN2, 1TR6 or D70 protocol through a U interface. The distance limitation of the NT1 from the Local Exchange depends on the distance supported by the Local Exchange.

To achieve system clock synchronization, configure the system as a slave to the local exchange. Derive the clock source from either the ISDN BRI Local Exchange connection or the other ISDN BRI/PRI/DTI local exchange connections, if available.

After you complete the acceptance testing setup, proceed with the test described in "Testing ISDN BRI functions" (page 87).

Figure 15 "ISDN BRI acceptance testing setup for trunking – TIE trunk connectivity" (page 51) illustrates one configuration that can be used to test ISDN BRI TIE trunk connectivity. In this configuration, a Meridian Customer Defined Networking (MCDN) TIE trunk connection is implemented by connecting two systems to the ISDN BRI leased line through the local exchange using two SILC cards. The S/T interface is connected to the local exchange using an NT1. There is no distance limitation on this configuration. System clock synchronization can be achieved by having
