Rate Multiplier

Position S6-7 is used to set the multiplier for the input timing. The unit can

operate at any data rate that is a multiple of 56 or 64 kbps. Selecting N

64K

provides port bit rates that are multiples of 64 kbps. The ones density requirements

of the T1 network line must be ensured in this mode. Selecting N

56K allows port

bit rates that are multiples of 56 kbps. The unit maintains ones density for the

selected DS0 channel in this mode.

S6-8

This switch is not used.

Rotary

Switch S7

This 10-position rotary switch works in conjunction with S6-7 and S4-8 to select

high-speed port bit rates. Switch S6-7 selects the rate multiplier as either N

64 or

56 (refer to Rate Multiplier in the previous paragraph).

Switch S4-8 selects either the Contiguous

or Alternate mode for the network DS0s

to carry data (refer to Channel Assignment in Configuration Switch S4 on page

2-3). Switch S4-5 is used to select the bit rates as shown in Table 2-6.
