|The TELESYNC TSI-1575
Modem/Network Test Unit provides a "dial up" means of determining
the throughput performance of an asynchronous V.90, K56flex, V.34,
V.32 modem and the associated telephone lines. The TSI-1575 network
connection to a DS-1 ISDN PRI interface. Configuration and control
of the TSI-1575 is through the RS-232C interface or the Ethernet 10BaseT
interface using a Telnet session.
Telephone numbers for
the DS-1 PRI can be provisioned at the CO Switch so all numbers
use all channels, or numbers can be restricted to particular groups
of channels. If desired, customers can call numbers in one block
of channels and field personnel dial numbers that access different
channels. In the TSI-1575, any telephone number can be assigned
to test for any tariffed rate.
The TSI-1575 supports
up to 23 simultaneous incoming and/or outgoing modem calls and performs
throughput performance analysis on each one independently. The TSI-1575
notifies the remote modem user of the speed of the connection and
whether the connection was equal to or greater than the tariffed
data rate. The customer received screen can be customized during
configuration of the TSI-1575. The TSI-1575 is also capable of originating
calls to modems and performing throughput analysis with control
using the RS-232C or 10BaseT interfaces.
The performance data on
the previous 200 calls is available through the RS-232C or Ethernet
interfaces. A separate previous 100 calls performance data log is
provided for failed calls. The logs can be searched based on calling
number or called number.
