WAN/SRV
The WAN/SRV setting identifies the card to which the output of this port is directed. If wan
is chosen, the data from this port will be directed to a WAN port (the options are w1-1 to
w4-2). If serv is chosen, the data will be directed to a port on a Resource card (the options are
P1, P2 and P3. P1 is FRS in slot P1, P2 is FRS in slot P2 and P3 is FRS in slot P3. After
selecting card, select logical port).
The only available rates available when routed to a server are 56K and 64K.
TS
The TS setting identifies the time slot on the WAN link to which this port is connected. Values
range from 01 to 24 for T1 links and 01 to31 (excluding TS 16 in cas or ccs mode) for E1 links.
For a display of the available time slots, refer to the cross-connect map for the WAN link.
FRAME
The Frame setting allows you to define the framing of the time slot connected to the OCU-DP
port. The options are a (DS0A), b-5 (DS0B) with a limit of five ports, b-10 (DS0B) with a
limit of 10 ports, and b-20 (DS0B) with a limit of 20 ports, as shown in Figure 3-2.
RATE
The Rate setting identifies the highest data transmission rate for the current port. Values are
2.4, 4.8, 9.6, 19.2, 56k, 64k, and sw56k (Switched 56 kbps). Figure 3-2 shows the various
rates. When the WAN/SRV option is set to P1, P2, or P3 (Four Server cards), the only valid
options for RATE are 56K and 64K.
SR TS
The Sub-Rate Time Slot (SR TS) indicates the subrate position within the DS0 time slot the
port will occupy (see Figure 3-3). If a framing is selected, only one subrate time slot is
supported and the SR TS setting will default to 1. If b-5 framing is selected, the subrate time
slots available are 1 to 5. If b-10 framing is selected, the subrate time slots available are 1 to
10. If b-20 framing is selected, the subrate time slots available are 1 to 20.
In b-5 framing, if circuits with speeds greater than 9.6 kbps are assigned to the subrate time
slot, adjacent subrate time slots must be available to accommodate their size. A 19.2 kbps
circuit would occupy two contiguous subrate time slots. This leaves space for up to three 9.6
kbps circuits from other OCU-DP cards and ports.
