APPLICATIONS
This Appendix presents the following network applications as
examples of how the TRMIM-20R may be used in a token ring
network. These are examples to help clarify features and
applications for the TRMIM-20R and actual applications are NOT
limited to those shown here.
• Adding to an existing Token Ring Network
• Separate Token Ring Networks in One MMAC
• Token Ring Networks Bridged Together
• MMAC with Ethernet and Token Ring Operating Simultaneously
B.1 ADDING TO AN EXISTING TOKEN RING NETWORK
Figure B-1 shows the addition of an MMAC with a TRMIM-22 and a
TRMIM-20R into an existing token ring network. Here, the
TRMIM-20R is used to insert an MMAC and its token ring products
into the ring. Any concentrator (with externally accessible trunk
ports) designed for use in an MMAC can be used. The Ring-In and
Ring-Out ports of the TRMIM-20R are connected to Ring-In and Ring-
Out ports of the adjacent concentrators. The existing token ring
network could consist of many vendors’ products.
