Adding and Modifying Connections

Use either the Cisco WAN Manager application or the CLI to add or modify connections. If you use the
WAN Manager application, refer to the Cisco WAN Manager Operations Guide.
This section describes how to add a connection to a PXM1 in a stand-alone shelf according to the rules
for a standard connection or a management connection in the form of either a three-segment connection
or a DAX con. See
addcon. If the application requires NSAP addressing, use addchan to add the connection and cnfchan
if you need to modify it. Refer to the command reference for the syntax. On the CESM CLI:
Add a connection through the preferred command addcon. (Alternatively, you can use addchan if your
Step 1
application requires the NSAP format of end-point specification.)
Execute addcon at both ends of the connection—unless the remote end-point is on port 34 of a PXM1
(see the note at the end of this step). The maximum number of connections for the AX-CESM-8T1 is
248 and 192 for the AX-CESM-8E1. Note that because you can add only one connection per port,
addcon does not request a connection number.
The system automatically assigns the next available channel number, so the addcon command does not
require it. However, some related commands require a channel number. To see the channel number after
you add a connection, use dspcons.
The syntax for addcon is:
addcon <port_num> <sig_type> <partial_fill> <cond_data> <cond_signalling> [controller_type]
[mastership] [remoteConnId]

Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
addred <redPrimarySlotNum> <redSecondarySlotNum> <RedType>
redPrimarySlotNum is the primary slot. For the redundancy bus (no bulk distribution),
valid slot numbers are 1–6, 9–14, 17–22, and 25–30. With bulk
distribution of T1 channels, do not specify 9, 10, 26, or 26.
redSecondarySlotNum is the secondary slot. For the redundancy bus (no bulk distribution),
valid slot numbers are 1–6, 9–14, 17–22, and 25–30. With bulk
distribution of T1 channels, do not specify 9, 10, 26, or 26.
RedType is the type of redundancy. A 1 specifies 1:1 for E1 with SMB
connectors. A 2 specifies 1:N for T1 or E1.
"Rules for Adding
port_num is the logical port number. This port must already exist (see addport).
sig_type is a number indicating the type of signalling: 1 specifies basic signalling,
2 specifies E1 CAS, 3 specifies ds1SFCAS (DS1 Superframe CAS), and 4 specifies ds1ESFCAS
(DS1 Extended Superframe CAS).
partial_fill is a number representing the number of bytes in a cell. It can be either 0 to specify that
the cell must contain 48 bytes or a non-0 value that fixes the number of bytes in each cell. For
structured E1, the partial_fill range is 20–47 bytes. For structured T1, the range is 25–47 bytes.
Unstructured T1 or E1 can be 33–47 bytes.
cond_data is the conditioning data in case of loss of signal (LOS). It is always 255 for unstructured
data transfer or 0–255 for structured data transfer. For a voice connection, the larger the cond_data
value, the louder the hiss heard in case of LOS.
