Table 1 and Table 2 list the functions and features of the TEM28
board.
Table 1 OTN Functions and features of the TEM28 board
Function and Feature
Description
Basic function
Coverts 24 channels of GE optical signals, GE electrical signals,
or FE electrical signals, and four channels of 10GE LAN/10GE WAN
optical signals to ODU0, ODU1, ODU2, or ODUflex electrical signals
with bandwidth not greater than 20 Gbit/s.
The reverse process is similar.
Client-side service type
FE: Ethernet service at a rate of 125 Mbit/s. Supports FE optical
signals and FE electrical signals.
GE: Ethernet service at a rate of 1.25 Gbit/s. Supports GE optical
signals and GE electrical signals.
10GE LAN: Ethernet service at a rate of 10.31 Gbit/s
NOTE:
The TEM28 board transmits FE or GE electrical signals, GE optical
signals, or 10GE optical signals on the client side.
When the TEM28 board transmits GE or FE electrical signals, to
facilitate fiber routing, you are advised to install electrical
modules at the RX27/TX27 and RX28/TX28 ports.
Cross-connect capabilities
Supports the cross-connection of a maximum of 16 channels of ODU0
signals, or 8 channels of ODUflex signals, or 8 channels of ODU1
signals, or 2 channels of ODU2 signals between the TEM28 board and
a cross-connect board by using the backplane.
OTN function
Supports the OTN frame format and overhead processing by referring
to the ITU-T G.709. The mapping process is compliant with ITU-T
G.709 and ITU-T G.7041.
Supports PM function for ODU0.
Supports PM function for ODU1.
Supports PM function for ODU2.
Supports PM function for ODUflex.
LPT function
Supported
NOTE:
The LPT function cannot be configured for EVPL services but only
for bidirectional EPL services (port <-> VCTRUNK). When the
LPT function is enabled, Source C-VLAN andSink C-VLAN of an EPL service must be left empty.
FE/GE electrical ports of the TEM28 board do not support the LPT
function.
FEC encoding
Not supported.
Alarms and performance events monitoring
Monitors BIP8 bytes (Poisson mode or Bursty mode) to help locate line failures.
Monitors parameters such as the bias current, temperature, and
optical power of the laser.
Monitors OTN alarms and performance events.
Provides remote monitoring (RMON) of the Ethernet service.
ALS function
Supports the ALS function on the client side.
NOTE:
ALS function is supported only when EPL services (port <->
VCTRUNK) are provisioned.
PRBS
Not supported
Physical clock
Supports synchronous Ethernet.
NOTE:
FE/GE electrical ports of the TEM28 board do not support the
physical clock function.
The board does not support the physical clock when it is
provisioned with 10G WAN services.
Test frame
Supported
Latency measurement
Not supported
Electrical-layer ASON
Supported
Protection scheme
Supports client 1+1 protection.
Supports ODUk SNCP.
NOTE:
Client 1+1 protection is supported only when EPL services (port
<-> VCTRUNK) are configured on the board.
