T1 AND E1 REMOTE ACCESS CONCENTRATORS
102
Perhaps this is what the Configuration Worksheet for our example network looks like:
Configuration Option
Setting
IP address for Concentrator
2.2.2.1
Phone number for Concentrator
(555) 555-1234
RADIUS or CSM on same subnet
as Concentrator?
Yes
Authentication:
CSM secret
CSM_sec
Concentrator name
Conc_LRA3
Concentrator secret
LRA3_sec
Concentrator password
LRA3_pw
Remote Device Name
RBridge
Secret/password for Device
secretbr
IP Address for Device
N/A
Phone Number for Device
N/A
This example requires proper setup of:
• The Concentrator (see
Section 6.4.1
),
• CSM (see
Section 6.4.2
), and
• The ISDN bridge. This part is very simple: Configure the device as a simple bridge and provide
the Concentrator network’s phone number: (555) 555-1234.
Standard PAP/CHAP/CLID authentication options are supported. There is no IP address assignment.
The Concentrator is not configured to call out (which is not supported anyway for this type of application).
