Roaming -- The ability to access a network anywhere and move freely while maintaining an active link through a wireless connection to a network. Roaming usually requires a handoff when a node (user) moves from one cell to another.

SS#7 - Signaling System # 7 - channel for network control - Signaling System # 7 - channel for network control

T-1 
1 Bell technology referring to a 1.544 Mbps communications circuit provided by long-distance carriers for voice or data transmission through the telephone hierarchy. Since the required framing bits do not carry data, actual T-1 throughput is 1.536 Mbps. T-1 lines may be divided into 24 64 Kbps channels. This circuit is common in North America. Elsewhere, the T-1 is supersede by the ITU-TTS designation DS-1. 2.. A 2.054 Mbps communications circuit provided by long-distance carriers in Europe for voice or data transmission. 1.
