I have a 512 mbps Leased line connection from BSNL, which is unframed from BSNL side. At my side, Fiber cable from BSNL is landed on CPE modem, TX and RX cables are connected from CPE modem to Junction box (LOOP TESTER), from LOOP TESTER to E1 modem, from E1 modem to V.35 modem, from V.35 to serial interface on CISCO my router. This is the topology i had now and its working fine.
But, now i want to place a VWIC 3 G.703 card on my CISCO router in the place of serial interface which i had now. I want to configure my VWIC 3 G.703 card as E1.
Any body please help me, from where i need to change my topology and configuration steps of VWIC 3 g.703 in CISCO router for my requirement.

Configure card-type E1, Under controller configure channel-group 0 unframed. Then corresponding serial interface. That's all.

Thank you for giving responce. I have configured as you told, but my the line protocol is goes down and reliability also 128/255 on interface. Please find below output.

Likely the e1 is nof unframed as you think but 8 timeslots for 512 kbps service. Would need to look in the interface converter configudation.

Thank for your suggesion. But at my service provider side they won't do framing.
Is framing is mandatory at my service provider side also?
I have a doubt on clock rate, should i mention clock rate?
I have crimped my 4 pair cable which is from CPE modem in 1,2,4,5 (1st pin - tx, 2nd pin - tx, 4rth pin - Rx and 5th pin - Rx) pins at RJ-45 jack and i connected it to my VWIC card. Is it correct which i have done?
Please help me as soon as posible. Because it is very urgent for me.
Please do needfull...
Thank you.
