Name of problem
Slow response experienced on PC when connected behind 1608 IP Deskphone
Products affected
1603SW, 1603SW-I, 1608, and 1608-I
Problem description
Customers may experience a slow response when using PC applications with their PC connected behind the 1608 IP Deskphone when
transferring large amounts of data or transferring very large files.
Customers with heavy data transfer usage or transferring very large files may experience slower response time than a PC
directly connected to a layer 2 switch.
Resolution
There is currently no fix planned for this issue, please use one of the workarounds defined below.
Workaround or alternative remediation
1. Directly connect the device to the layer 2 switch.
2. Increase packet size - Applications that allow the configuration of packet/frame size can be increased up to 1.5kb.
3. Upgrade the phone to a 1616 or a 9600 model phone
Remarks
Note:
The 1608 has all the "must-have" features of a deskphone and is the phone of choice for enterprises looking for an extremely cost
effective deskphone for large numbers of general purpose (Everyday) users.
Description: Clarifying PC data throughput using the 1608 10/100 switched Ethernet port.
The Avaya 1600 IP Deskphone Series, also referred to as the Avaya one-X Value Edition Phones, compliments Avaya’s more fully
featured 9600 IP Deskphone Series by addressing Enterprises who require a quality telephone with solid audio performance and broad
telephony feature support, but without the extras that higher end IP Deskphones deliver such as color displays, Gigabit Ethernet
interface, wide band audio and application enablement to name a few. The 1600 Series meets most customer expectations and
performs well for common office use.
It has been reported by a few customers that in some user cases, particularly in scenarios of high data traffic volumes, the performance
of the 1608 has an average throughput rate, below what a 1616 or a 9600 IP Deskphone can provide. This average throughput rate in
the high data traffic scenario is also true for the 1603SW-I, which shares the same design architecture as the 1608.
A device that supports an "Ethernet 10/100 line interface" (a 10/100 capable device) refers to the ability to connect to the 10/100
protocol and communicate on 10/100 networks. This does not refer to the speed of which it can communicate – the actual
throughput. Many Avaya and competitor phone models have 10/100 interfaces, but this does not guarantee the device on average can
pass through data at full interface occupancy (Full "line speed") of 100mbits/second. Avaya’s 1616-I and 9600 IP Deskphones support
users with high data traffic processing requirements.
Improvements to the throughput performance on 1600 Series have been included in previous software releases, and it is recommended
that customers update phones to use the latest firmware. Even with these improvements, the 1608 and 1603SW-I model will not
support data throughput to the level provided by the 1616-I and 9600 Series IP Deskphones. For customers who are using a co-
located PC connected to the LAN through the IP Deskphone, and who have high data traffic requirements including frequent file
transfers or sharing of very large files, it is recommended to use a 1616-I or 9600 Series IP Deskphone model to avoid the perceived
PC slowness that can result when using a 1608-I or 1603SW-I IP Deskphones.
