Sru Card State Status - Zhone IMACS 8000 User Manual

LD-SRU Card User Screens and Settings
3. Speeds of 0.3, 1.2, and 14.4 are not supported for synchronous channels (except 14.4 sync
with FRAME set to adpcm or hlink).
4. Communication Configuration is a three step process. This field will show n/a when sync
is chosen as the INTF option.
5. Delay Optimization is not available on LD-SRU*10 because it is already maximized for
throughput.
6. Majority Error Correction is a two step process. You will only see the choices off and on.
When on is chosen, the other alternatives will appear.
STATE
The State setting determines whether the port is active or inactive. Set this field to stdby
(standby) for ports that are not to be used or that have not yet been configured. Set it to actv
(active) for ports that are ready for use. The control leads assume the status shown in Table
16-3 for the different states.

CTS
WAN
The WAN setting identifies the WAN link assigned to this port. It is not necessary for ports on
the same card to be assigned to the same WAN link, or to contiguous time slots on a WAN link
(see the restriction in the TS field below).
TS
The Time Slot 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 to 31 (excluding time slot 16 when CCS or
CAS is used) for E1 links. The SRU card can further subdivide the WAN time slot into smaller
segments for transmission of low-speed data. Each WAN time slot can be further divided into
a maximum of twenty 2.4 kbps time slots (see Figure 16-4).
The only restriction to assigning WAN time slots is that the same time slot number on different
WANs cannot be used for subrate data ports on the same SRU card. For example, if you assign
time slot 1 on WAN 1-1 to one port on an individual card, you cannot assign time slot 1 on any
other WAN link to other ports on the same card.
