Introduction
Features and Benefits
Features and Benefits
The Access Navigator provides the ability to concentrate and groom a mix of voice and data information.
The 1/0 crossconnect functionality of the DCS allows data channels from a variety of locations to be
crossconnected and packed into dedicated T1s. The time slot interchange (TSI) functionality of the GR-303
system dynamically assigns voice traffic to the local digital switch. These two functions significantly reduce
the number of switch ports and T1s required to backhaul both voice and data traffic.
DCS, GR-303, and P-Phone benefits include:
l Voice and data concentration
l Voice and data grooming
l GR-303 line concentration of 4:1 TDM ISDN BRI services
l GR-303 line concentration of Nortel P-Phone (EBS) services from CA’s Adit® terminals
