Page 4: Operational Safety
DTR-4630 OPERATIONAL SAFETY WARNING Operation of electronic equipment involves the use of voltages and currents that may be dangerous to human life. Note that under certain conditions dangerous potentials may exist in some circuits when power controls are in the OFF position. -
Page 5: General Description
2 With WDM option fitted for combined use on a single fibre, optical path loss is reduced by approximately 2dB. 3 With WDM option fitted, when operating as a pair, one DTR-4630 must be fitted with a 1310nm laser and the other a 1550nm laser. -

< 5.0 VA. Other: Temperature range 0 - 50° C ambient. Mechanical For mounting in IRT 19" rack chassis with input, output and power connections on the rear panel. Finish Front panel Grey, black lettering & red IRT logo. Rear assembly Detachable silk-screened PCB with direct mount connectors to Eurocard and external signals. -
Page 7: Configuration
When using TRAPS via SNMP, depending on how system is set up, in order to avoid double reporting of alarms via the DTR-4630 card and the CDM card (SNMP Agent) of the frame, major and minor SNMP alarms that are reported to the CDM card of the frame can be disabled. -
Page 8: Installation
Signal Connections: The default setting of the DTR-4630 is to automatically operate at either 2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI or 270 Mb/s SD-SDI / ASI signals and do not require any adjustment prior to use, with the exception of link and DIP switch options described in the Configuration section of this manual that also allow SD only, HD/SD only or reclocker bypass modes of operation. -
Page 9: Optical Connections
When operating the DTR-4630 as a pair with the WDM option fitted, one unit must be fitted with a 1310nm (or 1260-1360nm) optical transceiver and the other with a 1550nm (or 1520-1600nm) optical transceiver. -

Page 11: Operation
OPERATION The DTR-4630 is primarily designed for use as an optical transmitter and receiver unit built into the one card, though it can be operated independently as an optical transmitter or optical receiver only device. The DTR-4630 is fully operable with previous IRT single channel 3G, HD or SD fibre links. -

Page 13: Snmp - What Is It
DTR-4630 SNMP What Is It? SNMP stands for Simple Network Management Protocol. It is an application layer protocol for managing IP (Internet Protocol) based systems. SNMP enables system administrators to manage system performance, and to find and solve system problems. SNMP runs over UDP (User Datagram Protocol), which in turn runs over IP. - Page 14 IRT modules that are SNMP compatible may need an optional plug-in SNMP module with a program relevant to the module that it is plugged into. Depending on the module, besides the module identification, parameters such as alarm states, inputs and controls etc.

Page 15: Dtr-4630 Snmp Functions
DTR-4630 SNMP Functions: When installed in an IRT frame fitted with SNMP capability, the DTR-4630 can be interrogated by an SNMP Network Management System (NMS). The DTR-4630 belongs to a series of fibre products that share a common framework and object identifier number (OID), when doing an SNMP ‘walk’... - Page 16 DTR-4630 - Control of the signal data rate setting: dataRateSet (1) sdi3G-HD-SD-ASI: Reclocker set to 3G-SDI, HD-SDI or SD-SDI/ASI rates. (2) sdiHD-SD-ASI-only: Reclocker set to HD-SDI (1.485 Gb/s) and SD-SDI/ASI (270 Mb/s) rates only. (3) sdiSD-ASI-only: Reclocker set to SD-SDI/ASI (270 Mb/s) rate only.
