Voice Quality GuidelinesThis section gives recommendations for increasing voice quality in VoIP configurations 10/100 BaseT
Although the TN802/B DEFINITY IP Interface technically supports 10/100 BaseT, 
testing and field experience have determined that superior voice quality and stability 
are achieved when the board is used at 10BaseT. Therefore, the IP Interface will be 
preset to 10 BaseT at the factory. Since this applications bandwidth needs are 
minimal, Lucent recommends that customers leave all IP Interface circuit packs set to 
10 BaseT. This supersedes any information previously published, including customer 
documentation.
LAN and Remote 
Access Parameters
Guidelines for LAN and remote access parameters that affect voice quality are 
available from the Lucent Customer Support web site at: http://support.lucent.com.
Note:These guidelines were not finalized at the time of publication of this 
document — they will be inserted here in future releases.
