Introduction
A system dependant delay constant is defined at the system configuration stage.
The MX8400 calculates the latency for individual Encoders and sets buffers
appropriately to ensure all Encoders within the system experience the same network
delay. This is achieved by ensuring the delay an Encoder service experiences is
equal to the predefined system delay constant.
An Encoder at a remote site will experience a larger delay in the network and is
therefore delayed less within the MX8400 input than an local based Encoder service
which is part of that the same Remote Reflex group.
