It is the customer’s responsibility to verify that other vendor’s equipment meets system-level compliance when installed in our chassis.

  • Page 106: Network Addresses

    Systems that use TL1 or require download functions must use 10BASE-T. 10Base-T also makes troubleshooting larger systems much easier. PairGain recommends that the Wideband System 3190 be placed on its own LAN. Any connection to a larger network should be done through a router with the appropriate firewall protection. Selecting the IP address, subnet mask, TCP/IP server address and trap addresses are basically arbitrary, but some understanding of these functions are still required to make an informed choice.

  • Page 107: Routers Or Gateways

    800-357-100-01, Revision 01 Appendix B - Technical Reference The subnet mask is also a 32-bit word, but it is generally a string of ones followed by a string of zeroes. Each subnet bit that has a one value identifies a corresponding bit of the IP address that is part of the netid. The zero bits identify the hostid.
