Key Feature: Call Admission Zone
• Customer and vendor call admission control enforced across all
network elements on Trunk ID basis
– Can manage CPS, RPS and session count across pool of VSXi systems
– Configured in single GUI screen
Example: CPS capped at 100 cps for TID
10,000 – managed across Co-Lo 1, 2, & 3

Key Feature: Network License
• VSXi “Network License Zone” shares a pool of session capacity
across a network of VSXi hardware
• Better support for geographic redundancy and distributed hardware
• Shown below: 6 nodes in 3 high availability pairs supporting 3
interconnect points - pool of sessions shared across all nodes

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
17
Introducing ROME
• HRS – High-speed Route Server
• Centralized management of Routes
– Simplifies route management
– Improves system operating performance
– Expands number of routes operators can manage
• Enables more sophisticated routing
– Enables simple & flexible jurisdictional determination
– Supports up to 50 alternative routes
18
ROME Operations
• Stateless server, routes held in RAM for
extremely fast processing
• Queried via SIP protocol
• Route uploads do not affect system CPS
• Server updated / managed via GUI and SOAP
• VSXi can recurse with TID mode
– Provides compatibility with variety of policy
servers (Nuestar Pathfinder, ATT, etc)
19
Functioning in the Network
• ROME can be added to existing VSXi network
ROME Accepts queries and provides
routes across INX nodes
