Add/Drop Application
You can use one of the EXTender 7000 WAN ports as an Add/Drop port, which can send traffic to another
network device.
Using the MI, specific DS0 channels of the T1/PRI Port_1 can be mapped to the Add/Drop port. This allows
traffic on those channels to remain unchanged while they are passed through the T1/PRI card to another
device on the network. For an example of the configuration required for a complete Add/Drop application,
see the
Add/Drop 6000 and 7000 application in t
he EXTender 7000 User’s Guide.
Note: Add/Drop application is only available when T1/PRI Port_1 is connected to a T1 Leased Line or a T1
Frame Relay Line
.
Add/Drop Configuration
WAN Port Setup
By default the T1/PRI Port_1 is the source port. Either WAN1 or WAN2 must be enabled prior to configuring
the Add/Drop port.
1.
Access the WAN menu using the following path:
MI Path
Configuration->WAN->WAN1
2.
Set the
Enable
to
Yes
. This will enable the selected WAN to receive data dropped from T1/PRI Port_1.
3.
Set
Mode
to
Sync-V.35.
4.
Set
Interface Type
to
DCE.
Note:
DCE is used in Add/Drop configurations (connecting to an EXTender 6000 or a Router). In DCE installa-
tions, you must use the 25 pin Female-to-Female crossover cable (DB-25, RS-530) that we provide.
5.
Access the
Sync Setup
parameter and enter the Sync Rate (bps). This is the bandwidth that has been
allocated to the Add/Drop Services.
Exampes:
T1 Leased configuration; the sum of DS0s assign as Add/Drop x DS0 rate
T1 Frame Relay configuration; the 'Maximum Bandwidth' assign in PVC setup for Add/Drop.

Enabling Add/Drop Service
Once the WAN port has been configured you need to enable Add/Drop on that WAN port. This is done by
using the Add/Drop services menu.

Access the
Add/Drop
menu using the following path:
