Since H12 is 1,920 Kbps, which is comprised of 30 B-channels, a 1,920-Kbps call can be carried only on an E1 facility. As with H11, the hunt algorithm uses a fixed allocation scheme with channel 1 being the fixed starting point. Hence, an H12 call is always carried on B-channels 1 through 15 and 17 through 31 on an E1 facility, as the following table shows. When the system is offered any other call other than a 1,536-Kbps call, the algorithm behaves as it does when H11 is optioned.
