Overview Plug-in Modules Applications Specifications

Interchangeable plug-in modules for REDCOM SLICE® 2100™


The basic SLICE 2100 unit has two T1/E1 digital spans, plus two 10/100 BaseT Ethernet ports (for up to 1,000 IP subscribers), and two PCMCIA slots for updates and database backup. SLICE 2100 also has two rear-accessible positions for interface modules. Either position can be equipped with a Line Module or a Line/ Trunk Module. To increase E1/T1 capability, one of these modules can be replaced with a Multi-E1/T1 Module. These modules can be replaced in the field with power applied.
