NetRunner WAN User’s Manual
Network Planning
2-2
Terminated or Switched
Utilizing these topologies, a NetRunner 500ET, 1000E, and 2000E,ED can
serve as either a terminated node (traffic is terminated in, or attached to the
local node) or a switching hub (no locally attached devices). The NetRunner
75E is designed as a feeder to a switched hub. Without local traffic
(data/voice/LAN), the NetRunner's WAN link capacity increases. The
following elements need to be considered when putting together a network:

Delay (varies be-
tween channel
type and proto-
col)
Due to delays, do not exceed six link hops in any net-
work path for units with voice/fax modules. Limit the
link hops to three (four nodes total) if you are configur-
ing
dynamic rate adaption on your voice/fax module.
Note:
Frame relay can be clocked to T1. A V.35 interface is required for
these higher rates.
