1.TST—4043 TST—4043由三个独立设备构成:(1)具有时间/频率分集功能的短波调制解调器;(2)前向纠错处理器;(3)密钥变化量为10~(80)的密码设备。该机可满足用户在使馆、商用或军用车、船、飞机内与电传机或传真设备进行自由通信的要求。4043通过V24或RS232接口直接与数据源终端相连。可设置成处理hSCII(8位)、Telex(5位)或慢速FAX代码方式。4043的另一端则通过一个0dbm 600欧的4线接口与短波无线电收发机相连。调制解调器所具有的冗余传
1.TST-4043 The TST-4043 consists of three separate devices: (1) a shortwave modem with time / frequency diversity capability; (2) a forward error correction processor; (3) a key variation of 10-80 ) Password device. The aircraft to meet the user in the embassy, commercial or military vehicles, ships, aircraft and fax machines or fax machines for free communication requirements. 4043 is connected directly to the data source terminal via the V24 or RS232 interface. Can be set to handle hSCII (8 bit), Telex (5 bit) or slow FAX code mode. The other end of the 4043 is connected to a shortwave radio via a 0dbm 600 ohm 4-wire interface. Modem with the redundancy pass
