Eight-Port Circuit Emulation Service Modules

Execute addred:

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.

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 “Rules for Adding Connections” earlier in this chapter. The preferred command is 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:

Step 1 Add a connection through the preferred command addcon. (Alternatively, you can use addchan if your 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]

•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.
