pathtrace based on Tenant ID sub-strings. When the majority input is discovered, the RSC will
parse the Tenant ID from one of the majority inputs, append its own CPU IP Address, and
transmit the newly created pathtrace string to its two outputs (primary/diversity).
Finally, the HUC module receives the primary/diversity reverse pathtrace strings into its FPGA
from its two DIF input connections. The HUC HCP then reports the received pathtrace strings
in its MIB for use by higher-level processes, as described in the following sections.
6.3.6 Pathtrace Detection/Reporting
On each node in the system, a Pathtrace Process is responsible for gathering up all the
pathtrace strings reported in the HCP MIB’s on its own CPU. The Pathtrace Process then
reports all the discovered pathtrace strings in its own Pathtrace MIB, which indicates the HCP
type, I2C/PCI address, MIB index, and pathtrace string value.
On each node in the system, a Node Paths Process is responsible for examining the Pathtrace
MIB, identifying valid, complete, and stable Tenant IDs, and reporting the results in the Node
Paths MIB in a manner that simplifies tenant processing algorithms.
On the Hub Master node, the Tenantscan process is responsible for examining the Node Paths
MIB’s on all nodes and determining whether the contents contain Tenant IDs that match
configured tenants in the system. If so, then the Hostname and IP Address tables in the Tenant
OAM are updated.
The Tenant processes in the Hub Master node are responsible for updating the Equipment MIB’s
on each node with the appropriate Tenant IDs and indices that are used on that node. The
Equipment Process then acts as the middle-level interface to the tenant hardware, reporting status
of all the hardware in the Status Table of the Equipment MIB and allowing hardware
configurations to occur via the Control Table of the Equipment MIB. Tenant processing in the
Hub Master node is the primary user of the Equipment MIB for status and control of tenant
hardware. The details of this are described in more detail in the following section.
7 TENANT CONFIGURATION
The Tenant OAM MIB is the primary interface for configuring the operating parameters of
tenants in the Digivance CXD system. The Tenant OAM MIB is used exclusively at the Hub
Master node, where any changes made to operating parameters are validated and pushed down
to the proper node(s) by Tenant processing.
7.1 Setting Protocol
transceptTenantOAMTable.transceptTenantProtocol
The Protocol field of the Tenant OAM MIB is an enumerated value, where the allowable
selections are the protocols supported by the Digivance CXD system, currently.
No Protocol (0), CDMA (1), TDMA (2), GSM (3), IDEN (4), AMPS (5), CW_WB (6),
CW_NB (7). In Composite Mode, protocol need not be selected, and defaults to No Protocol
(0).
