All rights reserved 8 Interface Capacity and Service Types DS1 Netmod  Structured mode:  1 to 24 DS0s per port  Unstructured mode:  Single DS1 per port Channelized DS3 Netmod  Structured mode:  1 to 672 DS0s per port  Unstructured mode:  Single DS3 per port  28 DS1s per port Channelized OC-3 Netmod/Port Card  Structured mode:  1 to 2,016 DS0s per port  Unstructured mode:  3 DS3s per port  84 DS1s per port Structured Service Unstructured Service

11 Copyright © 2005 Marconi Corporation plc. All rights reserved 11 Port Numbering  DS1 CES netmods use the same ForeThought port numbering format as cell netmods: 1A1  Ch DS3 CES netmods use a hybrid port numbering format to identify channelized interfaces on a physical port  DSX3 interfaces = port: 2b1  DSX1 interfaces = port(DS1 channel in DS3): 2b1(1)  DS0 interfaces = port(DS1 channel in DS3, DS0 in DS1): 2b1(1,1)  Ch OC-3 CES netmods/port cards use a hybrid port numbering format to identify channelized interfaces on a physical port  DSX3 interfaces = port[SONET path]: 4C1[1]  DSX1 interfaces = port[SONET path](virtual tributary group, virtual tributary): 4C2[2](1,1)  DS0 interfaces = port[SONET path](virtual tributary group, virtual tributary, DS0): 4C3[3](1,2,3)
