2.048Mbps Wireless Modem

T1 CSU/DSU Applications

In most T1 applications, the 2.048Mbps Wireless Modem replaces the CSU/DSU (or OCU) used in regular wired connections.

Figure B-6. T1/DSU Network Interface

This type of connection is referred to as “DSU network connection”. In order to meet the applicable pulse mask requirements of the DSX-1 standard, the Pulse Shape Parameter should be set according to the line length.

Figure B-7. T1/CSU Network Interface

In several applications, the modem may be connected to CSU/DSU equipment, as shown in Figure B-7. This type of connection may be chosen because of a technical (e.g., a special MUX interface not supported by 2.048Mbps Wireless Modem) or some other reason. This type of connection is referred to as a “CSU network connection”, and the Line Length Parameters menu should be set accordingly (option 6).
