Following BT’s ongoing 21CN rollout, it is only a matter of time before traditional constant bit rate services at the edge of the network are replaced by packet based IP services.  While this will enable considerably more bandwidth to be delivered in a more cost effective manner, it will also disrupt the way that synchronisation is delivered to the edge of the network.  Without good fit-for-purpose sync, many legacy applications will suffer with severe degradation to quality of service and in some cases may not work at all.

Chronos has launched a new sync testing service aimed at equipment manufacturers and service providers who will be focusing on Next Generation Network (NGN) services and solutions.

The Chronos NGN Sync Susceptibility and Testing Service is targeted at component and equipment manufacturers who are designing edge of network NGN products as well as service providers and equipment manufacturers who are placing applications at the edge of the network.

The former group of users includes semiconductor designers who are evolving new products some of which are addressing the new IEEE 1588 technology. Testing can be carried out to identify the sync transport quality of the technology.

Equipment manufacturers of products such as ATM Switches, DSLAMs (Digital Subscriber Loop Add Drop Multiplexers), MSANs (Multi-Service Access Nodes), Soft Switches or SHDSL modems will need to know whether their products meet sync transport criteria of professional applications which are deployed at the edge of a network, for example, GSM and 3 G base stations.

An example of buffer wander in an ATM switch is shown in Fig (1) with an enlarged portion in Fig (2). This particular switch was deemed to be not “fit-for-purpose” for connecting a mobile base station to the backhaul network using E1 circuit emulation.
