The following DTE combinations are D4SL/D8SL modules, MP-2100/2104 available: chassis with MSL-8 modules or MP-4100 Multiple data rates in the range of 64 to chassis with the M8SL or ASMi-54C/N 4608 kbps are supported. The data rates • Serial Port (V.35, X.21, RS-530) + LAN modules. depend on the line interface, DTE • E1 + LAN interface types, and operating clock User-configurable low-speed mode is • E1 + serial port (V.35, X.21, RS-530). modes. available for units with serial and LAN interfaces. In this mode ASMi-52 operates Note: T1 multiplexer units are not available. ASMi-52 employs standard SHDSL TC-PAM at 64/128 kbps (2-wire) and technology to extend the transmission 4-wire line interface modems can be 128/256 kbps (4-wire) data rates when range (see Table 1), thus enabling carriers configured to operate over 2-wire lines. working with devices with E1 DTE to reach more customers at lower costs. The modem uses an Embedded Operation interface. The maximum data rate in The following DTE interfaces are available: Channel (EOC) for controlling and low-speed mode is 2048 kbps.
