ADTRAN DE-4E specifications Control Port Operation, Abbreviation Definition

5. CONTROL PORT OPERATION

The FT1 DP provides a faceplate-mounted DB-9 connector that supplies an RS-232 interface for connection to a controlling terminal. The pinout of the DB-9 is illustrated in Figure 5.

The terminal interface operates at data rates from

2.4 kbps to 19.2 kbps. The asynchronous data format

is fixed at 8 data bits, no parity, and 1 stop bit. The supported terminal type is VT-100 or compatible.

NOTE

If you are using a personal computer (PC) with terminal emulation capability, be sure to disable any power saving programs. Otherwise, communication between the PC and the HDSL unit may be disrupted, resulting
