We have seen a recent increase in customers asking us for a faster upstream bandwidth solution for their Internet service for a range of reasons.
The rapid growth of Hosted Voice Services and SIP Trunking has seen a corresponding increase in the need for greater upload speeds. Because ADSL 2+ is limited to maximum of 1Mb upload speed this becomes a bottleneck for Hosted Voice services with high user numbers. A 1mb upload speed roughly equates to a limit of 10 -12 simultaneous Hosted PBX phone calls. As SHDSL plans are available with up to 10mb/10mb (10mb download and 10Mb upload speeds) SHDSL broadband is the answer to providing Hosted Voice call quality to offices with more than 10 staff.
Many corporate customers use SIP trunking for their Voice services. By having dedicated SHDSL internet SIP trunks get guaranteed Upload speeds which translates in to digital quality SIP calls for many more services than can be accommodated on ADSL..
Similarly SHDSL Internet provides the answer for many Small Business's that are using onsite web and mail servers which require a upload capacity than can be provided by ADSL Internet.
The biggest increase in SHDSL Broadband users we have seen is in companies requiring remote access to their networks. Each time a remote request for information is received by the server, it has to upload that information to the remote user. Because ADSL can only send or receive data alternately(ADSL is either sending or receiving but at vastly slower speeds on upload) this causes slow downs across the network for all other users. By moving to SHDSL internet for Remote access applications, This removes the upload bottleneck and provides for faster delivery of data and content.
The big benefit of quality SHDSL services is that they can be delivered as a dedicated 1:1 service meaning the user is quarantined from most other network limiters. eg Because the user is the only customer on that service, there is no slow down on your service due to the usage patterns of other users in your area. Another important factor is that SHDSL has capacity to send and receive at the same time while ADSL can only send or receive...one at a time.
