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.
Down: N × 64 K Up: N × 56K
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
N × 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
.
