Configuring T1 and E1 Trunk Modules
Configuring T1 or E1 module connections
The administrator enables ds1-atm interface 4. Because the interface has a default
nailed group number of 854, this value does not need to be set.
admin> read ds1-atm { 1 18 4}
DS1-ATM/{ shelf-1 trunk-module-2 4 } read
admin> set enabled = yes
admin> write
DS1-ATM/{ shelf-1 trunk-module-2 4 } written
3
Configure the ADSL port. (See Chapter 7, "Configuring the ADSL Line
Interfaces," for additional information.)
admin> read al-dmt { 1 1 5}
AL-DMT/{ shelf-1 slot-1 5 } read
admin> set enabled = yes
admin> write
AL-DMT/{ shelf-1 slot-1 5 } written
4
Create a connection profile.
The administrator creates a connection profile named uni-conn to associate the
DS1-ATM interface (nailed group 854) with the ADSL port (nailed group 5). The
default encapsulation method, atm-circuit, is used.
admin> new connection uni-conn
CONNECTION/uni-conn read
admin> set active = yes
admin> set atm-options nailed = 5
admin> set atm-options vpi = 0
admin> set atm-options vci = 36
admin> set atm-connect = 854
admin> set atm-connect vpi = 0
admin> set atm-connect vci = 36
admin> write
CONNECTION/uni-conn written
Note
If necessary, different VPI-VCI settings can be used in the connection profile.
To modify the VPI-VCI values for the ADSL port, change the settings of the
atm-options vpi and vci parameters. To modify the VPI-VCI values for the T1 or E1
interface, change the settings of the atm-connect vpi and vci parameters. For
additional information, see the Stinger ATM Configuration Guide.
Typical IMA configuration
This example illustrates how to create a group of interfaces using the first three DS1
links. The interfaces are assigned the IMA group name ima1, and nailed group
number 851. A connection to a subscriber link on port 9 is set up. The subscriber link
has the nailed group number 9.
Figure 9-5 shows the type of linkage that the IMA configuration creates.
