Page 99: Subtelegram Timing
USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE A.3.1 Subtelegram timing EnOcean Radio Protocol 1 (ERP1) and EnOcean Radio Protocol 2 (ERP2) uses a repeater-level dependent time slot mechanism for the subtelegram timing during transmission. -
Page 100: Tx Maturity Time
Identical subtelegrams from the same sender are considered to belong to the same telegram if they are received within the RX maturity time. In EnOcean radio systems using standard subtelegram timing (as shown in Table 43), the RX maturity time is 100 milliseconds. In EnOcean radio systems using compressed subtelegram timing (as shown in Table 44), the RX maturity time is 50 milliseconds. -
Page 101: Addressing
Telegrams where the intended receiver is designated are called Addressed Data Tele- gram or ADT in short. Telegrams where the intended receiver is not designated are called Broadcast Telegrams. Different types of addresses can be used to designate sender and receiver of an EnOcean radio telegram. A.4.1 Address types... -
Page 102: Eurid (Radio Id)
A.4.4 Base ID Normally, EnOcean devices will use their own EURID in order to identify themselves as the originator of transmitted telegrams. For very specific use cases, they can instead choose to use an address (ID) from within a defined range of 128 addresses. These 128 addresses are called the Base ID Range of the device. -

USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE A.6.1 Telegram chaining for broadcast telegrams Chained broadcast telegrams can be identified by the R-ORG 0x40 (CDM). The first telegram in a chain (with IDX = 0b000000) uses the CHAIN_LEN field to specify the total length of the DATA payload that is transported by this chain. -

Page 111: Telegram Chaining For Addressed Secure Telegram (Adt Sec_Cdm)
The last SEC_CDM telegram might therefore be split into two ad- dressed SEC_CDM telegrams due to the addition of the R-ORG and DESTINATION EURID addressing fields resulting in a telegram size larger than the maximum size of EnOcean radio telegrams. -

USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE Telegram encryption The goal of telegram encryption is to prevent unauthorized receivers from correctly inter- preting the content of a telegram. In order to do so, the original (plain text) data is encrypted with a security key thus trans- forming it into encrypted, unreadable data. - Page 114 USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE Conceptually the correspondence between telegram content and telegram signature is like the one between a person and a fingerprint: Each person has a unique fingerprint.

Page 115: Replay Protection
USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE Replay protection One fundamental problem with both telegram encryption and telegram authorization is that using the same input data (plain text) with the same security key will always result in the same encrypted data and the same signature. - Page 116 USER MANUAL TCM 515 / TCM 515U / TCM 515J – ENOCEAN TRANSCEIVER GATEWAY MODULE TCM 515 uses an approach where the RLC is used to change the security material (specifi- cally, the initialization vector – often called Nonce - used by the security algorithms together with the security key) to ensure that the encrypted telegram payload and the telegram sig- nature change even when the content of the telegram itself stays the same.
