Take a look at Kentrox's AAC-3 Access Concentrators and Multiplexers, I have used it in many T1-IMA solutions. http://www.kentrox/products/index.html -----Original Message----- From: Jesper Skriver [mailto:jesper@skriver.dk] Sent: Friday, September 18, 1998 2:57 AM To: nanog@merit.edu Cc: tdk-backbone@t.dk Subject: How to loadshare over many E1 links Hi, How would you loadshare over many (>6) parallel E1 links. Currently we do it by connecting them directly to the Cisco's in each end, and do CEF based per-packet loadsharing, it works fine, but support a max of 6 E1's ... I've been thinking om something similar to the Larscom inverse MUX (http://www.larscom.com/t3ft3/t3_megae.htm), but this one only support 4 E1's, then I can use multiple i-mux's and loadshare over the 8M links they provide, but it seems like a poor solution. Yes, I do know that a E3 would be a far better choice, but our ADM (Add-Drop-Multiplexer??) at this specific location only support E1's :-( /Jesper -- Jesper Skriver (JS249-RIPE), Network manager Tele Danmark DataNet, IP section (AS3292) One Unix to rule them all, One Resolver to find them, One IP to bring them all and in the zone to bind them.
