The minimum required MPLS network throughout for TPoP communication is 100 kbps. MPLS path redun-
dancy is recommended and the path switchover time should be minimized through appropriate measures.

Clock Synchronization

3.5.12
Overview
An external clock can synchronize the system-internal clock. The clock synchronization input (binary input1
(BI1) or USYNC) on the ALR module (pin A1 or C3) is provided for this application. Either an external synchroni-
zation pulse is connected (jumpering X14-X15) or the input is alternatively configurable as an input for
entering IRIG-B signals (jumpering X16-X17). For further information, refer to
Module and to Alarm Module

Comments
VLAN for TPoP service (command and RM telegram)
Checked: VLAN is enabled
Unchecked: VLAN is disabled
VLAN is disabled by default. If VLAN is enabled:
VLAN ID = 1, Priority = 0 by default.
ToS Precedence = 0 by default
IEEE 802.1Q VLAN ID.
Possible value: 1 to 4094
VLAN ID = 1
VLAN ID = 1 means the default Port VLAN Identifier (PVID) value is used for classi-
fying frames ingress through a Bridge Port. It is recommended to change PVID
(Port VLAN Identifier) = 1 by Equipment Management Operation. Working with
factory default VID = 1 in all switches of the same L2 Broadcast Domain leads to
the fact that no VLAN is working!
VLAN ID = 2 to 4094
VLAN Identifiers for general use as a PVID (Port VLAN Identifier) or a member of a
VID Set.
IEEE 802.1Q Priority.
Possible value: 0 (lowest) to 7 (highest)
CoS7 is typically allocated to or is used for network internal OAM traffic and
should not be assigned to customers edge traffic.
CoS6 is recommended for the highest teleprotection command traffic.
Type of Service value in IP header.
Possible value for Precedence: 0 (lowest) to 7 (highest)
Possible value for TOS: Normal | Minimum cost | Maximum reliability |
Maximum throughput | Minimum delay
Differentiated Services Code Point (DSCP) in IP header.
Default value is 0.
DSCP = EF (46) is recommended for the highest priority teleprotection command
traffic.
Hex value of the whole ToS byte in IP header
Default value is 0.
Possible value: 0x00 to 0xFF
