Page 21: Description
It also includes an integral modem which supports access to the CSU/DSU as well as other co-located equipment such as routers. The NetPath 100 can be factory optioned to include an ISDN Adapter (4 BRIs, for Backup and/or Bandwidth On- Demand).
Page 22: Isdn Adapter Option
2 Description ISDN Adapter The NetPath 100 can be factory-optioned to include an integral ISDN Adapter module. Option The ISDN adapter includes four “U” ISDN TA Interfaces with two integral NT1 In- verse Multiplexers, thereby providing up to 512 Kbps of switched connectivity for net- work Backup and/or additional Bandwidth On-Demand.
Page 23: Isdn Bandwidth
Bandwidth On-Demand provides an additional network connection for a second DTE On-Demand (router) port based on a request from the DTE. In this configuration the NetPath 100 ISDN Adapter is protocol-transparent. The Router determines the protocol used. A typical network configuration showing simultaneous Bandwidth On-Demand and Backup connections is shown in Figure 2-3.

System software can be downloaded to the NetPath 100 for upgrades. The front and rear panels of the basic NetPath 100 are shown in Figure 2-4 and Figure 2-5. Detailed descriptions of the NetPath 100 indicators and controls are provided in sec- tion 5 Diagnostics of this manual.

Page 51: Operation
NetPath 100 Options such as the ISDN Adapter. Configuration NetPath 100 configuration consists of initially setting the T1, CSU parameters and the WAN Management Channel’s DLCI address via the rear panel DIP Switches, via dial- in VT-100 console connection or via direct connected VT-100 terminal. These param- eters can also be reconfigured via in-band Telnet Management session after the initial installation.
Page 52: Power On
If operation looks normal, proceed with DIP Switch Configurations. NOTE: If the Dial Line has not been connected to the NetPath 100 prior to powering the unit on, the unit will issue a Dial Line Failure In-Band Trap to the Trap Manager after it completes its Modem and Dial Line self test.

Alarms NetPath 100 generates “traps” (SNMP alarms or alerts) in response to certain detected network conditions. The traps are reported either In-band utilizing the Management PVC, or via Dial-Out utilizing the internal Modem. Alarm conditions are also dis- played on NetPath 100 status screens and on front panel indicators.

Page 114: Management Access
Dial-In When using a PC (desktop or laptop) to establish management access to a NetPath 100, ensure that the VT-100 configuration is set to use flow control, and that the BAUD rate does not exceed 57600 (56Kbps). Some emulation programs will automatically configure to the highest rates available (such as 115200), and this may cause the dropping of characters while NetPath is re- turning a screen to the PC terminal.
Page 115 If so, perform a GET on the SNMPSetExecutionStatus object to determine the reason access was denied. 11. You can now access any SNMP object in the NetPath 100 MIB and perform a SET on the object, including objects in the Config, ResetStats and TimeEventCmd groups.
