Hello M.metwally,


you can follow the config guide for HWIC 4 GSHDL


http://www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/shdslfm.html


from your pdf:

mode : cpe means CO on other side

4 wire : important means usage of 2 pairsof wires

2-Pair groups—2 DSL pairs

From above link:

>> Cisco G.SHDSL HWICs support up to four pairs of digital subscriber lines (DSL): two inverse multiplexing over ATM (IMA) lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.

G.SHDSL HWICs support the following DSL groups:

Inverse Multiplexing over ATM (IMA) groups—1- 4 DSL pairs

Multi-Pair Operation (M-Pair) groups—2 or more DSL pairs

2-Pair groups—2 DSL pairs

1-Pair groups—1 DSL pair


pay attention to cables other users have had problem to figure the correct cabling.


Cisco HWIC-4SHDSL—Use a standard RJ-45 straight-through cable to establish connection between the HWIC and a network device.

vpi/cpi : 8/35  ATM parameters for the ATM PVC to be used to talk with CO.


RFC 1483 bridged: means that ethernet frames are carried within ATM AAL5 PDUs

this requires use of RBE or IRB to be implemented


IRB means that the ATM interface has no ip address but it is given to the BVI interface, the L3 object of the bridge-group


bridge 1 protocol iee

bridge 1 route ip


int atm0

no ip address

bridge-group 1

pvc 8/35

enc aal5snap


int bvi1

desc L3 ip address here can be manually set of get from a DHCP server

ip address ...


Hope to help

Giuseppe
