Using VWIC-2MFT-xxx or HWIC-4T1/E1, in both cases, CAB-E1-RJ45BNC.
Regarding NM-E3/T3, you cannot connect it to E1 interfaces. Subrate does not mean doing that.

Hello Gregory,
you need a so called balun that implements a conversion from RJ-45 120 ohm to BNC pair 75 ohm
see

Hope to help

Baluns are not necessary anymore. The referenced cable is not a balun, just a phisical adapter,
The Cisco 4-Port Clear Channel T1/E1 HWIC is software-configurable between E1 or T1 operation, balanced or unbalanced E1 termination, and CSU/DSU

Same is true for all currently produced cards.

Hi
Not connecting to E3, the ISP is providing 2- E1's for a total of 4M BW......the NM-1T3/E3 was the only module I found in the cataloge but I didnt know if it supported subrate (4M) traffic.
thx

It does support subrate. You will need 12.3(8)T IOS.
As mentioned before. T3/E3 subrate DOES NOT allow to connect a T1 or E1 circuit.

Hi Paolo,
So, does it have to connect to a T3/ET to subrate?

He have to use one of T1/E1 cards indicated above, to connect the E1 circuits.

so options......
I will be getting 2 seperate E1's from the ISP on cable. They will use PPP to combine into 4M usable BW.
1) I can use the 4-Port Clear Channel T1/E1 High-Speed WAN Interface Card (RJ jack interface), I will still need to convert from BNC to ENet? correct? or
2) Use the NM-1T3/E3 with the 12.3(8)T IOS? cable interface....correct on both or is one incorrect?

Yes, as indicated before.

Use the cable indicated before.
2) Use the NM-1T3/E3 with the 12.3(8)T IOS? cable interface....correct on both or is one incorrect?
Cannot use NM-1T3/E3, as indicated before.
