MOH port

The MOH (messages-, or music-, on-hold) connector — located on the Base Cabinet’s right side — is a standard

/8″ monophonic mini-jack, used for loading custom MOH recordings or for playing live music-on-hold from an

external source such as a CD player.

Maintenance/SMDR serial port

The Maintenance/SMDR port is a standard DB9 female serial connector, located on the Base Cabinet’s right side.

Use a standard shielded serial cable, DB9-to-DB9, for printer-to-computer; this is usually male-to-female.

Note: The maximum distance from the cabinet is 100 ft.

The output from the Maintenance/SMDR port is, 8 data bits, 1 stop bit, and no parity. The pinout is:

Data Transmit Pin 2

Receive Pin 3

Ground Pin 5

To program this port, use Function 18 as described in the ESI-50L Programming Manual (ESI #0450-1137).

Range: Programmable for 300, 1,200, 2,400, 4,800, 9,600, 19,200, 38,400, 57,600, or 115,200 bps.

Default: 38.4K.

Maintenance

Connect a PC (such as a laptop) to the port to perform on-line programming and diagnostics. Also, the

system sends reports to this port.

SMDR

The ESI Communications Server continuously outputs real-time SMDR call records to the port.

Note: The system will buffer up to 1,000 SMDR records in non-volatile memory when the Maintenance/ SMDR

serial port is in use for programming or uploading (such as during use of ESI System Programmer). If the

buffer becomes full, the system will discard the oldest records.

For more information about the Maintenance/SMDR port, see “SMDR” in the ESI-50L Programming Manual

(ESI #0450-1137).
