Use the corresponding numbers to enter the configuration mode for the various attributes.
The following attributes (at a minimum) should be configured:
Switch Protocol: The switch type specified by the Telco.
♦
Call Type: Specify either 64 k or 56 k data (depending on the type of circuit).
♦
SPID1, SPID2, LDN1, LDN2: If applicable, assign the SPIDs and LDNs provided by the
Telco.
♦
Dial Options: V.25.
♦
V.25: V.25 HDLC (if using sync serial) or V.25 ASYNC (if using async serial).
♦
DTE options: Synchronous (if using sync serial) or Asynchronous (if using async serial).
♦
Bit Rate: 128000 (or 112000 for 56 k calls).
♦
Protocol: PPP asyn−sync.
♦
Method: Multilink.
♦
We recommend that you refer to the ISU Data Sheet/Manuals on the ADTRAN web site
for the
possible options for each parameter. The example shown above should work for most situations.

Router Configuration and Testing
Use the following procedure to configure and test the router.
Connect a V.35 or RS−232 DTE Cable to the router serial port. Refer to the section Cabling for more
information on the types of cable you should use.
1.
Use show controller serial x (which indicates the type of cable the router is connected to) to verify
that the cable on the router side is DTE. For example:
Router#show controller serial 1
HD unit 1, idb = 0xCF6E8, driver structure at 0xD4A30
buffer size 1524 HD unit 1, RS−232 DTE cable
cpb = 0xE3, eda = 0x940, cda = 0x800
...
...
You should also verify that the connector type setting on the ADTRAN (option 16 in the example
above) matches the cabling used.
2.
Configure the router as follows:
username peer password 0 cisco
!
interface Serial1
ip address 192.168.180.2 255.255.255.0
encapsulation ppp
dialer in−band
!−−− Enable V.25bis dialing.
dialer map ip 192.168.180.22 name peer 5551111&5551112
!−−− Dialer map for the peer.
!−−− Note the multiple numbers separated by "&"
dialer−group 1
pulse−time 1
