Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05

Throughput Test

The outdoor SPI-2210 provides a throughput test for the backhaul to the ACR. The outdoor

SPI-2210 supports a server and client function for throughput tests.

The operator can set up target IP addresses, test duration, and bandwidths for throughput

tests, and check throughput and loss as test results. However, as the throughput test affects

system performance and call services, it is recommended not to perform the test during in-

service.

System Log Control

The outdoor SPI-2210 provides a log and log control function per application.

An application log can be created by an operator command or its debug level can be set.

The operator can usually keep the log function disabled, and when the log function is

necessary, he can change the debug level (Very Calm, Calm, Normal, Detail, Very Detail)

to enable logging and log save functions.

However, enabling log functions for many applications while the outdoor SPI-2210 is

running may affect the system performance.

Disabling Zero Code Suppression (ZCS)

The outdoor SPI-2210 collects statistics data and generates statistics files periodically.

The WSM collects these statistics files. A statistics file is composed of the header used to

indicate a statistics group and its detailed index (for example, a specific carrier, sector, CPU,

port, etc.) and the statistics data for that index.

In a statistics period, the statistics data for a specific index can become zero in a statistics

file in the following cases:

 When the index does not actually exist in the configuration.

 When the index exists in the configuration but its statistics data collected during that

period is zero.

Therefore, the Disabling ZCS function, which sets the zero data flag in the sub index

header, is provided to recognize the two cases separately.

2.2.6 Function of Supporting the Outdoor Environment

The outdoor SPI-2210 controls the temperature inside the system, collects and reports the

environmental alarms to operate normally in the outdoor environment. Thus, the outdoor

SPI-2210 can operate in the outdoor environment without any special equipment.

Especially, the outdoor SPI-2210 has the structure of the Direct Air Cooling System

(DACS) which consists of the membrane filter and the Heater and Damper Module (HDM),

and it supports the outdoor environment with low power consumption by optimizing the air

flow.
