Cisco Confidential 38 Network Factors Affecting T.38 Faxing Packet Loss - the amount of packets that are unsuccessful in arriving at the destination. Jitter - the measure of the variability over time of the latency across a network. Delay or Latency - the amount of time it takes a packet to travel from source to destination. © 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential 39 Packet Loss Fax calls are generally more susceptible to packet loss than voice calls. Ideally no packet loss should occur during a T.38 call. For networks where packet loss is a problem then multiple layers of redundancy are available for T.38. Enabling T.38 redundancy has the effect of more bandwidth being consumed per call.

Cisco Confidential High-speed Bandwidth Consumed Redundancy Level (Approximate) 0 25 kbps 1 41 kbps 2 57 kbps 40 Jitter Cisco voice gateways handle jitter through playout buffers with a default setting of 300 ms. With playout buffers this deep, only excessive jitter (> 300 ms) is a problem for T.38 on Cisco gateways. © 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential 41 Delay Delay is not as impacting to FoIP compared to VoIP. As long as the delay as constant without excessive jitter, then T.38 fax calls have been known to handle network delays of 1 second or more. However, as a best practice it is still recommended to minimize network delays as much as reasonably possible. Enough delay can cause FoIP calls to fail. Multiple IP and PSTN hops are prime sources of additional delay PSTN IP © 2007 Cisco Systems, Inc. All rights reserved. PSTN Cisco Confidential Satellite links cause large amounts of delay IP 42 QOS Policy for FoIP A QOS policy that prioritizes FoIP traffic will minimize packet loss, jitter, and delay.

Cisco Confidential 47 Redundancy and Failover (Part 1) With the H.323 or SIP call control protocols, gateways can be honed to multiple fax servers with varying levels of priority. In a normal scenario, incoming fax calls are simply routed to a local fax server. For example, the RTP voice gateway routes all calls to the local fax server and does not use the other available fax servers. © 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential Vianen Seattle Sydney IP RTP PSTN 48 Redundancy and Failover (Part 2) If the local fax server in RTP is unavailable, the voice gateway can route incoming FoIP calls to an alternate server, such as San Jose. Or calls can be spread between multiple fax servers and in a load sharing manner. The voice gateway can handle many different levels of preferences and load sharing for complex implementations. © 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential Vianen Seattle Sydney IP RTP PSTN 49 Redundancy and Failover (Part 3) Gateway can be configured to use ICMP pings to monitor the reachability of a fax server. Vianen As long as fax server responds to pings then fax calls are routed to it. If pings become unsuccessful then the gateway routes calls to alternate servers. Automatic failback occurs when pings are successful again. © 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential Seattle IP Sydney ICMP ICMP Pings Pings RTP PSTN 50 Redundancy and Failover (Part 4) Gateway can also failover based on configurable disconnect cause codes. Vianen If the fax server is fully loaded without any free channels, then it will return a disconnect cause code of “user busy” for each subsequent FoIP call. Instead of failing the call, the gateway can reroute the call to an alternate fax server. © 2007 Cisco Systems, Inc. All rights reserved.

If a current VoIP infrastructure exists then a FoIP deployment can utilize the same QOS policies. Packet loss, jitter, and delay should be minimized for FoIP and interface queuing mechanisms such as LLQ can help. Voice gateways have a number of different redundancy and failover features for communicating with multiple fax servers.
