Alcatel Carrier Internetworking Solutions 7270 MSC - Manual (Page 2)

Technical Summary
Cell Relay Services
> High performance virtual circuit (VC) and
virtual path (VP) switched virtual
connections (SVCs), soft permanent virtual
circuits (S-PVCs), and permanent virtual
circuits (PVCs) capabilities
> A wide range of interface speeds from
DS0 to OC-3/STM-1
> Supports UNI 3.1, UNI 4.0, and PNNI
> 1+1 automatic protection switching for all
optical interfaces
> Standard service interworking functions
for connections that terminate on frame
relay or circuit emulation endpoints
Frame Relay Services
> All frame relay interfaces are configurable
for UNI, NNI, PPP or transparent HDLC
> Frame relay/ATM network interworking
(FRF.5) and service interworking (FRF.8)
> Four QoS levels for differentiated frame
relay services
> Supports PVCs and frame relay SVCs
> Supports IP-aware frame relay
> HDLC frame forwarding for transport
of legacy protocols (PPP, X.25, SNA)
Circuit Emulation (Private Line) Services
> Uses circuit emulation card to transport
private lines and other TDM traffic over
a broadband infrastructure
> Consolidates T1 or E1 PBX trunks and
hybrid circuits over a broadband
infrastructure
> Supports point-to-point or point-to-multipoint
services
> Provides integrated DCS functionality
Voice Services
> Proxy signaling interface to an external
softswitch
> Compressed voice (G.729A, G.726
(32K ADPCM), G.711)
> QSIG and N-ISDN signaling for PBX
networking
> Integral echo cancellation and silence
suppression
IP Services
> IP routing and forwarding capabilities
> Differentiated IP CoS to subscribers
for all service types
> Dynamic OSPFv2 routing
> Supports IP-VPNs
> Up to 768 virtual routers
> VLAN support (802.1Q)
> VC to VC forwarding
> IP over ATM, FR or Ethernet
> Supports transparent LANS, and remote
LAN segments
> Self-learning LAN bridge
> Spanning Tree protocol
> RFC 1483 Ethernet over ATM
encapsulation
