Distributed TeleCombus Core Card Application
The system assumes a distributed system model with only NSE device present locally. There is no
local SBS device and the SBS driver is not required. The OPA module is hosted by the core card.
The system assumes TeleCombus mode of operation. Path termination mode is HPT. ILC is
assumed to be used as the primary mean of system page swapping.
Module Initialization Vector: nbcsInitMivDistCoreTelecombus
This profile can be used to set the system in a distributed TeleCombus mode with a 1-stage time-
space-time fabric in a NSE core card:

Distributed TeleCombus Line Card Application
The system assumes a distributed system model with SBS devices present locally. There is no
local NSE device and the NSE driver is not required. The OPA module is also disabled in the line
card. The system assumes TeleCombus mode of operation. Path termination mode is HPT. ILC is
assumed to be used as the primary mean of system page swapping.
the multiframe is 48
ILC threshold for all ports are 250 microseconds
ILC FIFO threshold is 1 data unit
all 12 timeslices are configured in LPT termination mode
ILC threshold for all ports are 250 microseconds
ILC FIFO threshold is 1 data unit
Bus type is TeleCombus
switching mode is column
Only NSE device driver is present and SBS driver is absent
standard fabric is assumed
standard OPA scheduling is selected
all connection map settings are automatically populated to the offline pages of the devices
all connection map page switching is controlled by ILC
all offline pages are automatically synchronized with the online connection page
all working/protect link selection in SBS devices are controlled by hardware pin
