Description

FRAME RELAY
 

  • APS-8, APS-16 and APS-24 provide access to public or private Frame Relay networks. Async data is sent directly over the Frame Relay or encapsulated over X.25 / Frame Relay (Annex G), to achieve maximum reliability.
  • A unique funneling mechanism adjusts feeder throughput to CIR levels.
  • LMI and ANSI PVC management protocols are supported and operation is in compliance with ANSI T1.606, T1.618, T1.617, Annex D, and ITU Rec. Q.922 Annex A.


X.25
 

  • X.25-configured links support permanent virtual circuits (PVCs) or switched virtual circuits (SVCs). Link packet size is up to
    4096 bytes.
  • APS-8, APS-16 and APS-24 support both mandatory and additional ITU X.25 facilities.
  • Dial-up X.25 links are supported via a dial-up modem controlled by a DTR signal or V.25 bis commands.
  • APS-8, APS-16 and APS-24 support X.25 multicasting.


X.32
 

  • APS-8, APS-16 and APS-24 support X.32 protocol for a dial-up X.25 link. This enables users to access an X.25 network remotely, via a dial-up modem with X.32, or to use the backup dial-up link for an X.25 or Frame Relay network.


HDLC TRANSPARENT ACCESS
 

  • Each of the three switch ports can be programmed to operate with transparent HDLC for connecting bridges, routers and other HDLC communication devices over X.25 or Frame Relay networks. The HDLC protocol is encapsulated over X.25 or Frame Relay, providing end-to-end transparent operation.


ASYNC ACCESS
 

  • All async channels can act according to X.3, X.28 and X.29 profiles at traffic speeds of up to 115.2 kbps. Async traffic can be packetized directly over a Frame Relay network, or packetized over the X.25 network. All channels are configured and monitored by the management agent of APS-8, APS-16 and APS-24.
  • Each one of the APS-8, APS-16 and APS-24 ports can be configured to SLIP or PPP modes, operating at data rates of up to 15.2 kbps.


IP ROUTING
 

  • IP datagrams can be routed over Ethernet, PPP or SLIP links and over Frame Relay networks (according to RFC 1490) or over an X.25 network (according to RFC 1356).
  • APS-8, APS-16 and APS-24 support RIP1, RIP2 and triggered acknowledgment RIP messages (according to RFC 1058, 1723 and 1724). The RIP support enables easy IP connection while minimizing IP user configuration. The triggered RIP enables reduction of the overhead associated with the RIP mechanism, by minimizing the number of periodic messages sent.
  • Static IP routing is supported. IP packets are routed to destination via SLIP, PPP, LAN (Ethernet), X.25 or Frame Relay link, according to the IP address.


ETHERNET
 

  • The Ethernet interface enables bridging and/or routing of LAN packets over a Frame Relay network (according to RFC 1490) and over an X.25 network (according to RFC 1356).


ISDN
 

  • PPP/Frame Relay/X.25 can be transmitted over the ISDN media.
  • ISDN support includes up to 128 kbps (Bundle two B channels).


NETWORK MANAGEMENT
 

  • APS-8, APS-16 and APS-24 contain an SNMP agent, which enables remote configuration, collection of statistics / status reports, and diagnostics. The management agent can be programmed to periodically send statistics and status reports to a maximum of five management stations.
  • Configuration, monitoring and controlling of all network resources can be performed from a RADview-PC or
    RADview-HPOV/UNIX SNMP management station.
  • A management station can be connected directly to APS-8,
    APS-16 and APS-24 through LAN, PPP or SLIP.
  • APS-8, APS-16 and APS-24 SNMP agent support private and standard MIBs, including MIB II with RFC 1213, RFC 1381 and RFC 1382 for X.25, and RFC 1315 for Frame Relay.


BACKUP
 

  • Enhanced backup facilities include PSTN/ISDN support.
  • Frame Relay, X.25 and PPP can be transmitted over the ISDN media.
  • APS-8, APS-16 and APS-24 features an automatic return to main link facility after a network recovery.
