GDC's Solution

Over the years, providers have sought a more efficient, highly reliable solution to provide interswitch transport. GDC's solutions provide NEBS Level III compliant, ultra reliable, high density, managed interaccess provisioning vehicles.

Initially, carriers deployed a channel bank to split the incoming T1 link.

Now, LECs and carriers provision the bandwidth via T1 circuits, using one 56/64 kbps timeslot for the signaling channel. Some smaller CLECs and other independents use 56/64 kbps DDS circuits for cost-saving reasons (Figure 2).

GDC's SpectraComm 5000 Series provides integrated T1/FT1 CSU/DSUs that eliminate the need for a channel bank. The SC 5001 serves as a channel bank for collocated SC 5520 DSU cards, which handle one DS0 each (Figure 3, Option A). The SC 5001/5520 architecture permits multiple SS7 links to share a common T1 facility. Alternatively, when optimum network redundancy and resiliency is required, the SC 553 may be used (Figure 3, Option B).

NEBS Compliance The SpectraComm shelf and all of its modules are NEBS Level III certified, thus assuring that GDC products can be deployed in all carrier central office environments.

Network Managed SpectraComm 5000 products are SNMP managed via the SpectraComm Manager Card (SCM), enabling network operators to proactively monitor the network for possible trouble spots and avoid downtime.
