Testing n x 64 kb/s services Application Note 1211-2 1 n x 64 kb/s traffic Wideband services such as videoconference, LAN interconnection, and high-speed computer links usually require a bandwidth greater than 64 kb/s, but maybe less than the full 2 Mb/s, for example, 384 kb/s. These wideband The most critical factor when using For example using a test set like the signals can be sent in a 30-channel 2 n x 64 kb/s aggregate channels is to Hewlett-Packard 37722A digital Mb/s frame by "sharing" the signal ensure all equipment is configured telecom analyzer or the HP 37732A between several "aggregated" for the same sequence of timeslots. telecom/datacom analyzer, a 64 kb/s channels.
