- We are considering installing a pair of Symplex Datamizer compressing
- TDMs, to optimise the use of an international leased line. However, we
- would like to find out others' experiences first. For those who don't
- know, the device is basically a TDM with a data compressor attatched to
- the aggregate channel.
-
- We would like to know of any good or bad experiences in the following
- areas:
-
- 1) Reliability:
-
- 2) Throughput: the local marketing people claim 4:1. From experiences
- with modems, I would guess that 2:1 is a better bet in
- the real world, but would like to hear what sorts of
- throughput people actually get.
-
- 3) Satelites: we want to use these over a satelite link. Does the
- increased latency have any nasty side-effects?
-
- The types of traffic that we plan to shove down the line include X.25,
- SL/IP or PPP and SNA (perhaps).
-
- If there are any other comments, or other products, I would appreciate
- the info. Mail or posting is great, and I will summarise any mail I get,
- if there seems to be any interest.
