Zhone Technologies Network Device manual BnR IP Concentrator Card

Zhone Technologies, Inc. IMACS Product Book, Version 4

Software-initiated diagnostics supported on the DS0-DP/G.703 card include the setting of local loop backs towards either the network or the attached DTE equipment. In addition, a remote loop back function allows the DS0- DP/G.703 card to generate four DDS-compatible latching loop back codes for the far-end OCU, CSU, DSU or DS0- DP equipment respectively. A time-out option authorizes the DS0-DP/G.703 port to automatically release the loop back after ten minutes.

7. BnR IP Concentrator Card

The 822860 BnR IP Concentrator card provides a means of concentrating network management data from up to 8 remote IMACS onto a single asynchronous SLIP link for connection to a NMS. Essentially the 822860 takes IP management data from the 8 B7R-formatted DSOs and concentrates it onto a single, asynchronous SLIP line which can then be connected to an asynchronous terminal server for connection to a LAN-based NMS.

Management information from remote IMACS systems can be directed to the IMACS containing the 822860 over the Facilities Data Link (FDL) or an ESF T1 link as shown in Figure 19. FDL is a 4 Kbps channel normally used to manage the T1 link. When the FDL is used to carry IMACS management data it is no longer able to carry T1 management data as well.
