What is the maximum number of T1/E1 trunks that DCOSS can support? How about T3 support?
A single DCOSS can support a maximum of 8 T1 or E1 or combination trunks. Current development plans will allow a maximum of 16 T1 or E1 or combination trunks by first quarter 2001. GL outlines many options for T3 support. T3 Option 1. Seven fully loaded (8 T1 trunks per DCOSS) DCOSS systems will yield 56 T1 trunks, which results in two T3s. This configuration can be designed as seven rack mount DCOSSs utilizing monitor/keyboard/mouse switching. With the introduction of the 16 trunk DCOSS, you will require three sixteen-trunk DCOSS systems and one eight-trunk DCOSS to accomplish the dual T3 configuration. The resultant of the T1s from the DCOSS will be sent to two multiplexers to yield a dual T3 hookup. T3 Option 2. A single DCOSS with eight T1 trunks and a series of GL multiport repeaters will yield two T3s. This option will rely on a single T1 transmission being broadcast to seven T1s. The resultant of the multiport repeaters will be sent to two multiplexers to yield a dual T3 hookup.
