Access Navigator / GR-303 + Data Host
Management Architecture
Management Architecture
Access Navigators provide management access via Ethernet SNMP, Telnet CLI, and RS-232 CLI. Valet™
and NetworkValet™ EMS software provides a graphical user interface (GUI) for SNMP management.
Flow-through provisioning of the remote Access Bank II and testing control over T1 connections reduce
truck rolls and monitors voice and data service availability at customer locations.
IP DS0 Management
The Access Navigator can use IP management commands and dedicated DS0s to manage up to 24
remote Adit 600 terminals. IP DS0 management uses a colocated Adit 600 terminal with an IP Router
card to redirect IP messages between the Access Navigator’s IP port and the 24 DS0s on a groom DS1.
The Access Navigator then cross-connects the groom DS0s to a dedicated drop DS0 going to each
remote Adit 600. Customers wishing to conserve IP addresses can use an Ethernet hub or router
providing port addresses translation (NAT) to isolate the IP DS0 management network.
