(ASCEND) Re: Direct Connection between Channelized E1 interfaces.

[jhyang <jhyang@nuri.net>]

 Thanks for your reponse.

 No, I don't want frame relay yet..
 B-STDX 9000 support HDLC encapsulation between F-R clouds.

 I want to make clear channels between F-R clouds.

    [R] ---- [F-R Clouds (ascend switches)] ----- [R']
        ^hdlc                               ^hdlc

 Ascend switches automatically converse between hdlc and frame relay
 framing.
