MST2 Transcoder


1U server with Sansay DSP card


Licensed on a network wide basis


Transcoding session count is tracked along
with but separate from NLZ


Provides added value for applications:


Long tail echo cancellation up to 728
msec


DTMF translations


T.38 translations

15

MST2 Transcoder (
cont
)


Highly scalable yet low cost per port


Add up to 4000 sessions per 1U rack space


N:1 redundant and NLZ make for lower TCO


Integrated into TID
config

for easy routing


Makes routing independent of codec concerns


Redundant RTP (RRTP) for best OTT quality


Video transcoding supported at limited size

16

TSX Transcoder


Integrated INX/MST2 for easier deployment


Has a new system type with limited functions


This is similar to Peering Edition;
ie
, lower cost


Still supports NLZ for redundancy and
building distributed networks


HA Redundant for highly reliable POPs


All DSP (audio) aspects are same as MST2
