Question on bonding 2 T1s with an Adtran TSU120e

Discussion in 'Cisco' started by Steve Pfister, Aug 28, 2003.

  1. My company is connected to our NY office via a T1 and an Adtran
    TSU120e. I think the setup is 9 channels for voice between our two
    PBXs and the rest for data.

    We are looking for options to expand the bandwidth between the two
    If we purchase a drop and insert module for both T1s, can we bond the
    two T1s together (i.e., get ~40 channels for data and 9 for voice)?
    That's the impression I get, but I just wanted to confirm that.

    I know it's been a while since you posted, but I wanted to let you know
    there is a better way.
    Where are you located (just curious)?

    Take out the TSU, install a Cisco router with a Voice trunk (configured with
    QoS) on each side. Now bandwidth is assigned dynamically so if no one is on
    the phone site-to-site you get it all for data, and the voice is compressed.
    If you still need more, add another T1 interface and bond them in the
    router. We've been doing this for years works great.
