The upper limit is moving target. At one time, narrowband meant 150 bps (that is 150 bits per second!). Then, the upper limit became 2,400 bps. Later, it moved to 64 Kbps. Contrast with wideband and broadband. digital cross connects ensure high performance and reliability of circuits within PCS networks. Alcatel's digital cross connect system optimizes network bandwidth and monitors the performance of all circuits connecting subscribers to the base switching stations. Continuous performance monitoring enables operators to correct network problems before they affect service.
