Mikrotik with DS3 (T3) interfaces (support - bonded ?)

Hardware MikroTik hardware general

I have three microwave towers with three DS3s passing through. I was using a dual-DS3 media converted to ethernet to get 90 Meg. I now need to use all three DS3s to get 135 meg throughput (3 * 45).

My questions:
#1 Does Mikrotik support DS3 (T3) cards if so what are they and do they work well?
#2 If there are DS3 cards supported in a Mikrotik, can they be bonded to get 135 meg throughput (three bonded DS3s) ?
#3 If I convert each DS3 to a 45 meg ethernet - there a good way to bond all three ethernets together so that I still get my desired 135 meg throughput ?

I am an ISP and this is my uplink internet feed, so I am looking for a stable solution.

I have not used anything beyond 433ah but I think the kind of hardware rb1100 is it should support a t3 line. and it is easier configured and routed than a cisco 3745 or similar routers which can take on a t3

  1. nope
  2. nope, see 1)
  3. yup. As long as the other side supports actual bonding (802.3ad is a protocol that must run on both sides) you can bond. See http://wiki.mikrotik.com/wiki/Manual:Interface/Bonding. If you can’t run actual bonding you can run PCC: http://wiki.mikrotik.com/wiki/Manual:PCC

RouterOS used to support the LMC / SBE T1 / DS3 cards… they were dropped in 4.14 I think…

I still have a single router running a SBE T1 card… but that will die this next week, as our warehouse is moving and I dropped a cable connection in..

10X the speed for 1/6 the price… I cant argue with that…

Long live the “T” … The “T” is dead…
