Frame Relay Physical Configuration
Begin the HSIM or CyberSWITCH physical configuration by accessing the WAN Physical 
Configuration
 screen through Local Management (
). Proceed with the following steps:
1.
Use the arrow keys to highlight the [WPIM X] field at the bottom of the screen. Press the 
SPACE bar to select the number of the WPIM to be configured, then press ENTER.
2.
Use the arrow keys to highlight the MgrType field. Configure the Protocol Manager Type as 
either Frame Relay Point to Multipoint (FR PtoMP), or Point to Point (FR PtoP). 
FR PtoMP and FR PtoP are the two settings for Frame Relay. Frame Relay Point to Point has one 
Interface per DLCI assigned when DLCIs are created by the Service Provider. In Frame Relay 
Point to Multipoint, there is one interface to multiple DLCIs, and the DLCIs are dynamically 
learned. When backing Up a Frame Relay Primary circuit it is best to configure the Frame Relay 
protocol manager for Point to Point mode. If the Primary Frame Relay interface has only one 
DLCI it can work in Point to Multi-Point mode.
The concept of a Manager for each configured protocol also exists. Each physical connection has 
one or more (more if a protocol is encapsulated, such as PPP encapsulated within ISDN) Protocol 
Managers that control protocol operation.
Point to MultiPoint Configuration (LM WAN Physical Configuration)
1.
Set the MgrType to FR PtoMP.
2.
If more than 32 DLCIs are required, set the Max VCs value (up to a maximum of 125 on the 
CSX400/HSIM-W6).
3.
The next IF will display the value that should be entered into the timeslots, if T1 or E1. This 
should be done now.
4.
Configure any other required physical parameters for that interface. Such as: Sync Port Type, 
or clock speeds (Sync WPIM), T1 or E1 timeslot configurations etc. REMEMBER: if using the 
Sync WPIM, always manually setup the Sync Clock Speeds to match the actual line 
configurations.
NOTE
The MAX VC value associated with a physical WAN interface is set to a default value 
based on the number of possible ports available and the protocol manager selected. If 
more PVCs/DLCIs exist than the default MAX VC value will allow, the MAX VCs may 
be changed.
