BUYING TIPS
- Speed Programmability: The multiplexer node from a PoP should
support the speeds desired by broadband/SME/corporate customers. It should
have the flexibility to support bandwidth provisioning through speed
programmability because customers might look to increase/decrease the
speeds.
- Time-of-day Programmability: The multiplexer should be able to
change the access circuit speed of a customer on the fly, depending on the
time-of-the-day requirements for bulk data transfer batch processing,
enquiry and response, as well as broadcasting requirements.
-
Media Support: The multiplexer should support
multiple options like copper, fiber, and radio in addition to point-to-point
and multipoint bandwidth provisioning. Different media support is essential
to meet speed and QoS requirements.
-
Support for Cards and Multiple-access Standards: Support
for different cards is necessary for future expansion of the network. The
multiplexer should also support all DSL interfaces through addition of
corresponding functional modules. It should also be capable of provisioning
both cable TV and gigabit Ethernet link.
-
Physical Interfaces Programming: With hierarchical
evolution of the network, its topology changes and therefore physical
interfaces on the network—both on the trunk side and the access side—require
frequent changes. Trunk interface programmability would take care of sudden
demands for bandwidth.
