PDF user manual for CopperEdge 150

'XDO3DWKZD\VRQD3RUWAll IADs provide data and voice access to upstream networksfor users downstream. But, although the data streams andvoice streams go over the same DSL line to and from the CE150,the data and voice packets are separated into two VCs on DSLlines and on DS1 and DS3 lines. Two pathways on the WAN interfacemust be created. Two paths over the CE150 are necessarybecause the voice packets must go to their own voicegateway and the data packets must go to their own data gateway.The voice gateway performs call setup and routes voicepackets; the data gateway reads header information and, in addition,routes data packets.'XDO1HWPRGHOVRQD3RUWTo accommodate the dual pathways over DSL ports and WANports on the CE150, dual netmodels are necessary. For example,on data VCs on DSL ports, you can use any of five netmodels:• IP• VWAN• CopperVPN• Cross-Connect• HDIAOn voice VCs on DSL ports, which must be set on VC 22, youcan use either of two netmodels:• Cross-Connect• HDIAThe procedures for configuring data VCs on the DSL ports forthe IP, VWAN, CopperVPN, and Cross-Connect netmodels arethe same as they have always been. Since you must set the netmodelon the port, you do not need a VC. The system uses a defaultof 528. In contrast, the procedures for configuring voiceVCs on the DSL ports for the HDIA netmodel are new and requiresome explanation. Special configuration of the IADs isnecessary.&KDSWHU9RLFHRYHU'6/
