2.3 TCC2P Card

Note For hardware specifications, see the
The TCC2P card is an enhanced version of the TCC2 card. For Software Release 5.0 and later, the
primary enhancements are Ethernet security features and 64K composite clock BITS timing. It also
supports E1 SDH external timing sources so that a SONET shelf can be deployed in a network using
SDH timing. SDH timing is typically used when the SONET platform is deployed for Au3 SDH
applications.
The TCC2P card performs system initialization, provisioning, alarm reporting, maintenance,
diagnostics, IP address detection/resolution, SONET SOH DCC/GCC termination, and system fault
detection for the ONS 15454. The TCC2P card also ensures that the system maintains Stratum 3
(Telcordia GR-253-CORE) timing requirements. It monitors the supply voltage of the system.
Note The LAN interface of the TCC2P card meets the standard Ethernet specifications by supporting a cable
length of 328 ft (100 m) at temperatures from 32 to 149 degrees Fahrenheit (0 to 65 degrees Celsius).
The interfaces can operate with a cable length of 32.8 ft (10 m) maximum at temperatures from –40 to
32 degrees Fahrenheit (–40 to 0 degrees Celsius).

TCC2 Power-Level Indicators
Definition
The PWR A LED is green when the voltage on supply input A is between the
low battery voltage (LWBATVG) and high battery voltage (HIBATVG)
thresholds. The LED is amber when the voltage on supply input A is between
the high battery voltage and extremely high battery voltage (EHIBATVG)
thresholds or between the low battery voltage and extremely low battery
voltage (ELWBATVG) thresholds. The LED is red when the voltage on
supply input A is above extremely high battery voltage or below extremely
low battery voltage thresholds.
The PWR B LED is green when the voltage on supply input B is between the
low battery voltage and high battery voltage thresholds. The LED is amber
when the voltage on supply input B is between the high battery voltage and
extremely high battery voltage thresholds or between the low battery voltage
and extremely low battery voltage thresholds. The LED is red when the
voltage on supply input B is above extremely high battery voltage or below
extremely low battery voltage thresholds.
