3. From the Dial-In Modem menu, choose:

Disable to disable connection of a dial-in modem to the control port Enable to enable connection of a dial-in modem to the control port.

Note If an ASCII terminal or PC is connected directly to the control port while the dial-in modem access option is enabled, signals from the terminal or PC may be confused with modem control signals by the Vmux-2100 modem auto detect capability and inadvertently cause the Vmux-2100 to disable the terminal or PC connection. To avoid this situation, verify that the Control port dial-in modem access is set to Disable (this is the default setting) before attempting to make a direct terminal or PC connection to the Control Port (this can be accomplished safely via Telnet). If dial-in modem access is not required, it is recommended to leave this option disabled.

Configuring Signaling Information

Vmux-2100 allows you to configure the signaling parameters according to the selected signaling mode: CAS for E1, Robbed Bit MF for T1 or CCS for E1/T1. Signaling mode is selected via the E1 Parameters menu of the voice card (see the Configuring External E1/T1 Ports section below).

•CAS/Robbed Bit MF – You must configure a signaling profile and signaling table associated with it (ABCD bits, idle code and OOS signals).

•CCS – When working with CCS-SS7, you can configure the fill-in packets flow by selecting the SS7 keep-alive suppression rate.

Configuring Signaling Profiles

If you are using CAS signaling, you must configure the signaling system of Vmux-2100 to make it compatible with the signaling method used by the PBXs connected to the voice E1/T1 ports. The management software allows you to manipulate the ABCD signaling bits and methods of representation of the idle code and out-of-service signals generated by the PBXs (see Table 4-1). Signaling conversion is used for connection of PBXs, which use different signaling formats.

You can store up to five signaling profiles; Vmux-2100 uses only one of them at a time. The signaling profile selection is performed via the E1 Parameters menu of the voice card (see the Configuring External E1/T1 Ports section below).

Note	The signaling profile configuration is available only for the units operating with CAS
	signaling.

To configure the signaling profile:

1.From the Management menu (see Figure 4-6), choose Signaling Configuration The Signaling Configuration menu appears (see Figure 4-15).
