Configuring Synchronous Devices on the Leased Line

The task in this section involves configuring equipment that is required by the leased-line topology that is introduced in Example of a Configuration for a Leased-Line Link. The synchronous devices that are required to connect to the leased line include the interface and modem.

Prerequisites for Synchronous Devices Setup

Before you perform the next procedure, you must have the following items:

• Working leased line that is installed at your site by the provider

• Synchronous unit (CSU/DSU)

• Oracle Solaris release installed on your system

• Synchronous interface card of the type that is required by your system

How to Configure Synchronous Devices

1. Physically install the interface card into the local machine, if necessary.

   Follow the instructions in the manufacturer's documentation.

2. Connect the cables from the CSU/DSU to the interface.

   If necessary, connect cables from the CSU/DSU to the leased-line jack or similar connector.

3. Configure the CSU/DSU, as instructed in the documentation from the manufacturer or network provider.

   Note - The provider from whom you rented the leased line might supply and configure the CSU/DSU for your link.

4. Configure the interface card, if necessary, as instructed in the interface documentation.

   The configuration of the interface card involves the creation of a startup script for the interface. The router at LocalCorp in the leased-line configuration that is shown in Figure 2-2 uses an HSI/P interface card.

   The following script, hsi-conf, starts the HSI/P interface.

   #!/bin/ksh
   /opt/SUNWconn/bin/hsip_init hihp1 speed=1536000 mode=fdx loopback=no \
   nrzi=no txc=txc rxc=rxc txd=txd rxd=rxd signal=no 2>&1 > /dev/null

   hihp1

   Indicates that HSI/P is the synchronous port used

   speed=1536000

   Set to indicate the speed of the CSU/DSU
