3. Fixed frequency offset generation on transmitted signals with maximum value of
±120 ppm as per ITU-T O.174 (11/2009) 8.2.1.
4. Sinusoidal wander generation on Ethernet interfaces following ITU-T O.174
Amendment 1 sections 8.4.2.1 and 84.2.2 and ITU-T O.174 (11/2009) section 8.4.
5. Generation, decoding and transparent forwarding (IP Through mode) of the
ESMC and the SSM code. Transmission and reception of “hear-beat” and event
SSM messages is subject to ITU-T G.8264 clauses 11.3.2.1 and 11.3.2.2.
6. QL to be transported by the SSM is encoded as specified in ITU-T G.781 clauses
5.5.2.1 (Option I), 5.5.2.2 (Option II) and 5.5.2.3 (Option III).
7. SSM messages are generated at port level. Source MAC address is set to the
local profile MAC address.
A.4.3. Power over Ethernet
1. PoE (IEEE 802.3af-2003) and PoE+ (IEEE 802.3at-2009) detection.
2. PoE interfaces: 10BASE-T, 100BASE-T and 1000BASE-TX through attached RJ-
45 ports A and B.
3. PoE pass-through when the equipment is configured in transparent (through)
operation mode.
4. PoE voltage between pairs 1-2 / 3-6 and 4-5 / 7-8 in endpoint test. Voltage and
current in pairs 1-2/ 3-6 and 4-5 / 7-8 in through mode.
A.5. Ethernet MAC
1. Ethernet MAC generation and analysis in Ethernet and IP Endpoint mode. Analy-
sis in Ethernet / IP Through mode.
2. Supported Ethernet frame formats: DIX, IEEE 802.1Q, IEEE 802.1ad.
3. Support for Jumbo frames with MTU up to 10 kB.
4. Setting of source and destination MAC addresses. For source MAC address,
users can choose between the factory default address or a user custom address.
Destination addresses can be configured as the opposite port factory default
address, a single custom address or an address range. If they are specified as a
range, the generated sequence will contain all the addresses within the configured
range.
5. Setting of the Type / Length value in ordinary Ethernet frames. Configuration of
the Type value is blocked if the user sets a frame structure requiring an specific
Ethernet payload type.
6. Enable / disable VLAN and Q-in-Q modes. In VLAN mode, the Type / Length
value is automatically set to 0x8100. In Q-in-Q mode, the Type / Length value is
set to one of 0x88a8, 0x8100, 0x9100, 0x9200 or 0x9300.
7. Configuration of the VLAN VID and User Priority if the VLAN encapsulation is ena-
bled.
