Switch Control Interface Benefits

Switch Control Interface Benefits

• Enables multiple bearer control systems to coexist

PNNI

MPLS

ISUP

• Enables multiple virtual networks to coexist on a single infrastructure

Wholesaling of switching/transmission


Media ControlMedia Control

• Support for Telephony Services on Packet Infrastructure

VoATM - AAL1, AAL2, AAL5, SVCs

VoIP - UDP, RTP, H.323, Precedence, RSVP, SIP


Media Control BenefitsMedia Control Benefits

• Common adaptation and control infrastructure for VoIP and VoATM

MeGaCoP used for both VoATM and VoIP

• Separate call and bearer control

More flexible delivery of voice transport

• Leverage existing IN model

Number translation, etc..
