DVB-over-IP streams (IP TX 1 and IP TX 2). Furthermore, if an EOP2000C01 module is installed in the slot immediately to the left of the IPA2000C01 then two auxiliary ASI inputs become available, and if an EOP2000C02 is installed immediately to the right, then two auxiliary ASI outputs become available.

SNMP management and the ability to record events in a file including date and time information for further analysis. The IPA2000C01 is a TL2000 terminal line module and can be housed in a two rack unit (2 RU) UR2000 mounting frame.
- Two DVB-ASI buses on the backplane of the mounting frame coming from an auxiliary module located in the slot immediately to the left of the IPA2000C01. - Two DVB-over-IP receivers (UDP and RTP with and without FEC) connected to two gigabit Ethernet interfaces.

• The IPA2000C01 module and the mounting frame should always be installed, maintained, operated and removed by personnel with sufficient technical qualifications. The equipment should never be placed in damp areas, near splashing liquid, or in explosive or corrosive atmospheres.
1 - Remove the blank panel covering the front of the empty slot chosen for installing the IPA2000C01 in the mounting frame. 2 - Insert the IPA2000C01 module into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame.
Albalá Ingenieros | Manual IPA2000C01 3.5. Interconnection The arrangement of the front panel connectors of the IPA2000C01 module is shown in the following figure. Front panel of the IPA2000C01 The IPA2000C01 module provides DVB-ASI Transport Stream input and outputs as well as Ethernet interfaces.
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest lengths because it is used to calculate the equalizers in the IPA2000C01. Cables carrying signal between the module and the devices should use single piece construction, avoiding spliced sections with double BNC female or barrel connectors.
Albalá Ingenieros | Manual IPA2000C01 4. OPERATION This section describes the significance of the front panel indicators of the IPA2000C01 module and their remote control and monitoring ability. 4.1. Front panel description The appearance of the front panel and the elements it contains are shown in the following illustration.
In order to avoid unnecessary switching, the recovery time after an error condition has been cleared can be programmed. By default this value is two seconds. Also, when an error is detected at the selected input, the IPA2000C01 only switches to a different input if that input is error-free.
• Output buffer: The IPA2000C01 includes a buffer at the output whose operation depends on the operation mode of the module: - DVB-T Mode: In this mode the user sets the network delay, equal to the delay that...

IPA2000C01 to the response time of the frame synchronization error detectors. When the IPA2000C01 operates in this mode the delay fields in the "General" tab of the control software display the delay of the transport streams received with respect to the 1 PPS reference signal. The delay is measured at the input of the output buffer after IP de-encapsulation.

If the difference in delay between the two signals is unknown, the information provided by the IPA2000C01's control software can be used to determine this value. In order to find the difference in delay the buffer must be set to a sufficiently large...
Albalá Ingenieros | Manual IPA2000C01 4.5. Module remote control and supervision The IPA2000C01 requires remote control for configuration. In order to perform remote configuration and supervision of the module an optional TLE2001C02 model remote communications controller must be installed in the mounting frame.
- Supervision of the status of the inputs and outputs. 4.5.1. Details of the IPA2000C01 registers The IPA2000C01 module provides control and status registers that can be read and written by means of specific commands described in the communication control module user manuals.

Albalá Ingenieros | Manual IPA2000C01 5. GLOSSARY DVB-ASI Asynchronous Serial Interface. An asynchronous serial interface for DVB streams that is one of the principal formats for transmission of MPEG-2 streams over cable. Forward Error Correction. This technique corrects errors at the receiving point produced in a digital transmission channel by including redundant information at the transmission point in the form of error correction codes.
