5.5 WAN/User Port Specifications
• 1 built-in serial port, configurable as user or link, supporting V.35/V.11, TIA-232
(V.24), X.21, X.21 EU, TIA-449 (V.36) and TIA-530 interfaces.
• Maximum speed without compression: 6 Mbps (6144 Kbps).
For a port with INTERNAL clocking, if the port speed is configured higher
than 2 Mbps (2048 Kbps), the clock speed will be 3 Mbps (3072 Kbps) or 6
Mbps (6144 Kbps), whichever is closer to the configured speed. For
EXTERNAL clocking all port speeds are supported.
•
Link port maximum speed with compression: 896 Kbps.
• HD-26 female connectors, gender and interface autodetect from custom HD-26
cables: V.35 DCE, V.35 DTE, X.21 DCE, X.21 DTE, X.21 EU DCE, X.21 EU DTE,
TIA-232 DCE, TIA-232 DTE, TIA-449 DCE, TIA-449 DTE, TIA-530 DCE, TIA-530
DTE.
• Circuits: either leased, switched or Frame Relay.
• Coding: NRZI or NRZ.
• WAN port protocols: synchronous full-duplex HDLC, Frame Relay (FR-USER for
network connection), RFC-1490.
• Synchronous user port protocols: HDLC, Synchronous PPP.
• Frame Relay protocols: Frame Relay User (FR-USER), Frame Relay Network
(FR-NET), RFC-1490, UNI-DTE, UNI-DCE.
• Frame Relay management: LMI, ANSI TI.617/Annex D, ITU-T Q.933/Annex A,
CLLM or disabled.
• PVC switching: 300 PVCs, automatic DLCI discovery.
• SVCs: Frame Relay telephony applications, one SVC per voice call.
• SNA: SDLC, LAN or Frame Relay RFC1490 (BAN, BNN); SDLC spoofing of up
to 64 PUs, type 1, 2.0, 2.1 and 4/5, local SDLC and LLC2 spoofing, SDLC-to-
LLC2 conversion.
• Asynchronous user port protocols: ENQ/ACK, XON/XOFF, CTS/DTR,
Transparent, Reliable, Asynchronous PPP.
