The list of layer 2 signaling parameters are listed in 

Layer 3 signaling parameters are listed in 

.

The BCM installs default settings for MBMs, which vary depending on the region chosen during 
start up. These settings for the R2MFC MBM can be verified and customized through either 
Element Manager or Unified Manager. Perform the following steps to verify and customize the 
PRI (internal) link:

1 Open the Element Manager. See the Administration guide for the host system for an 

explanation of how to use Element Manager.

2 Connect to the BCM you are trying to administer.

Protocol

ETSI Euro-ISDN (ETS 300 102). The R2MFC 

MBM upper board is the NETWORK side, so the 

BCM must be configured as USER side.

Incoming calls from CO to BCM - Digit dialing 

mode

Overlap. Every digit is passed to the BCM; the 

BCM determines when the number is complete. 

The call can be set up immediately after the last 

digit is dialed.

Outgoing calls from BCM to CO - Digit dialing 

mode

Overlap - for systems requiring second dial tone 

from the R2MFC MBM.

Bearer capability for calls initiated by BCM

R2MFC MBM accepts bearer capability 

requests of services: voice, audio, fax, modem.

Bearer capability for calls initiated from the 

R2MFC MBM to the BCM

Bearer capability indicates a normal voice 

service.
