Table A-8 Timing Requirements
Loop Preferred timing source unless a private line is used.
Network If the unit is set for loop timing and the network received
signal is lost, timing automatically reverts to Internal.
Internal If using private line applications, set one DSU/CSU to
Internal.
DATA01 Nx64 kHz or 2048 kHz
A-4 Solo E1 DSU User Guide—June 1998
The unit is designed to facilitate the maintenance of the line and
troubleshooting of problems by incorporating comprehensive diagnostics
tools into the unit. In most cases, these tools will eliminate the need for test
equipment when diagnosing network problems.
Telnet and SNMP Management
The Solo E1 DSU supports the industry-standard Telnet and Simple
Network Management Protocol (SNMP) Management Information Base
(MIB II). Full embedded SNMP agent through SNMPv1, supporting RFC
1213, RFC 1406, MIB II, with enterprise MIB.
Telnet through the COMM port operates at one of the following baud
rates: 1200, 2400, 4800, 9600, 14400, 19200, 28800, and 38400.
