Setting the DSU Mode for the Serial Interface
In interface configuration mode, define the data service unit (DSU) interoperability mode by entering
the
dsu mode [0 | 1 | 2 | 3 | 4]
configuration command, as in the following example:
Router(config-if)#
dsu mode 1
Use the
no
form of this command to return to the default, 0.
The local DSU mode must match the remote DSU or T3 port configuration. For example, if an ADC
Kentrox DSU is at the remote end of the T3 link, then the local T3 port must be configured for mode 1.
You need to know what type of DSU is at the remote T3 end to find out if it interoperates with the
PA-MC-T3-EC. Specify mode 0 for connection from a PA-MC-T3-EC to another PA-MC-T3-EC or a
Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-MC-T3-EC to a Kentrox DSU.
Specify mode 2 for connection from a PA-MC-T3-EC to a Larscom DSU. See
Table 4-1
for a list of
DSUs and their corresponding bandwidth ranges.
Note
If the far-end DSU has more than one DTE (HSSI) port, connect to and configure only DTE#1. See
Caution below for Verilink DSUs.
Caution
Always connect to and configure HSSI port B on the Verilink HDM 2182. Port A is not supported by the
PA-MC-T3-EC.
