E&M interface

An E&M interface sends and receives E&M signals. It can be connected to a PBX to provide audio transmission functions. Table 7-327 describes the attributes of an E&M interface.

Table 7-327 Attributes of an E&M interface

Attribute	Description
Connector type	RJ45
Standards compliance	G.712
Interface rate	64 kbit/s
Protocols	Routing mode: Bell 1, Bell 2, Bell 3, Bell 4, and Bell 5 PBX mode: Bell 5
Interface frequency	201 Hz to 3513 Hz
Cable type	E&M Trunk Cable

DIP Switch Usage Instructions

Interfaces on a 6E&M card can work normally only after you turn the corresponding dual in-line package switches (DIP switches) to 2-wire or 4-wire mode. Figure 7-147 shows the DIP switches on a 6E&M card.

Figure 7-147 DIP switches

Use tweezers to operate the DIP switches.
On a DIP switch, the position close to ON DIP (top) represents 1, and the position close to 1 2 3 4 (bottom) represents 0.

After you turn the DIP switch of an E&M interface to 2-wire or 4-wire mode, the E&M interface can work normally. Table 7-328 describes the DIP switches on a 6E&M card.

Table 7-328 Description of DIP switches

Interface Number	DIP Switch	Lines	Description	Factory Setting
E&M0	SW101	1001: 2-wire mode 0110: 4-wire mode	2-wire mode: bars 1 and 4 are in the ON position; bars 2 and 3 are in the OFF position. 4-wire mode: bars 1 and 4 are in the OFF position; bars 2 and 3 are in the ON position.	4-wire mode
E&M1	SW100
E&M2	SW102
E&M3	SW103
E&M4	SW1
E&M5	SW2
