MINI DACS
z 2, 3, or 4 ports, E1, T1, or DTE (2 DTE Max.)
z For E1/ T1, each DS0 time slot from any port can be assigned to any DS0 time slot of any other port
z For E1/ T1, each DS0 can be designated as a 64 Kbps clear channel, or as a voice channel.
z Full translation of digitized voice between T1 and E1, including A law to law and signaling bits association.
z 2-line by 16-character LCD for maintenance, performance monitoring, and administration
z Ethernet port for the connection to SNMP and to Telnet
z Inband Subnet Management facility for remote management through national networks.
Multicolor LED indicators for each of 4 line interfaces
Loop-V4300 Mini DACS E1/T1 converter provides both DS0 and n x 64 Kbps cross-connect between any T1 and E1 ports and E1 to T1 format conversion functions. E1 to T1 conversion include line format, A law tolaw conversion, and signaling bits
association. Loop-V4300 also supports a DTE port operating from 56 Kbps to 1984 Kbps, This unit is suitable for applications involving 2 or 4 ports. Loop-V4300 also supports inband Management, where management data is carried in a DS0 time slot, the same way as user data, traversing national networks.
To order specify: Note: RoHS compliant units are identified by the letter G appearing immediately at the end of ordering code.
