WAN features

The G350 supports the following WAN features. The G250 also supports these features, except where otherwise noted.

●Traffic shaping. The traffic shaping function estimates the parameters of the incoming traffic and takes action if it measures traffic exceeding agreed parameters. The action could be to drop the packets or mark them as being high drop priority.

●PPP over channeled and fractional E1/T1. The G250/G350 has the ability to map several PPP sessions to a single E1/T1 interface.

●

Note:

The G250 only supports fractional E1/T1.

PPPover Universal Serial Port PPPoE

Unframed E1 for enabling full 2.048 Mbps bandwidth usage

Point-to-Point Frame Relay encapsulation over channelized/fractional/unframed E1/T1 ports or over a Universal Serial Port interface

●Frame Relay LMI types supported: ANSI (Annex D), ITU-T:Q-933 (Annex A0), LMI-Rev1, and No LMI

●

●

Backup functionality supported between any type of Serial Layer 2 interface

Dynamic Call Admission Control (CAC) for Fast Ethernet, Serial, and GRE tunnel interfaces. Dynamic CAC provides enhanced control over WAN bandwidth. When Dynamic CAC is enabled on an interface, the G250/G350 informs the MGC of the actual bandwidth of the interface and tells the MGC to block calls when the bandwidth is exhausted.

●Quality of Service (QoS). The G250/G350 uses Weighted Fair VoIP Queuing (WFVQ) as the default queuing mode for WAN interfaces. WFVQ combines weighted fair queuing (WFQ) for data streams and priority VoIP queuing to provide the real-time response time that is required for VoIP. The G250/G350 also supports the VoIP Queue and Priority Queue legacy queuing methods.

●Weighted Random Early Detection (WRED). The G250/G350 uses WRED on its ingress and egress queues to improve the performance of the network when overloaded. The purpose of WRED is to indicate to transmitting hosts to reduce their transmission speed when the ingress G350 queues are congested.

●Policy. Each interface on the G250/G350 can have four active policy lists:

-Ingress Access Control List

-Ingress QoS List

-Egress Access Control List
