Physical Partitioning with Dial-In and Dial-Out Scenario
The following is a bidirectional dial scenario using a Cisco AS5300 access server. Two modem pools are
configured. One modem pool contains 84 56K MICA modems, which is shared by 400 remote
salespeople who dial in to headquarters. The other modem pool contains 12 fax-capable modems, which
are shared by 40 employees who dial out of the headquarters LAN using the Cisco DialOut Utility
software. See Figure 20 for the network topology.
The following hardware configuration is used on the Cisco AS5300:
• One 4-port T1 PRI card
• Two 48-port cards containing fourteen 6-port MICA 56K modem modules and two 6-port MICA
fax-capable modem modules
To configure physical partitioning with dial-in and dial-out capability, perform the following steps:
Step 1 Create the 56K modem pool for the 400 remote salespeople. This modem pool contains 84 modems,
which are reserved for the dial-in calls. To get access, the salespeople dial the DNIS 5550303. The total
number of simultaneous calls is limited to 84. The 85th call and those above it are rejected. The modem
dialin line configuration command is used to prevent modems 1 to 84 from dialing out.
