1.5.13.2 End-to-End Delay
The data path end-to-end delay, which is a function of
all connections and network parameters, is calculated
as follows:
End-to-End Delay = PDVT + Packet Creation Time +
Fixed Network Delay
where PDVT is measured in seconds, Packet Creation
Time is measured in seconds, and time of one time slot
= 1/8kHz.
SAToP (Unstructured) Packets:

Packet Creation Time
SB
(NTS 64K) 8bit
=

×
where SB = size of packet in bytes.
CESoPSN Packets (Structured or Structured with CAS):
Packet Creation Time = 0.125ms x NF
where NF = number of TDM frames per packet.
1.5.14 End-to-End Alarm Generation
An end-to-end alarm generation mechanism exists in the
EV kit to facilitate the following alarms:
• Unframed: OOS is transmitted towards the near-end
TDM interface in the event of:
far-end LOS, AIS
PDVT underflow/overflow
• Fractional: Time slot/CAS configurable alarm pattern
is transmitted towards the near-end TDM interface in
the event of:
far-end LOS, LOF, AIS
PDVT underflow/overflow
1.5.15 Default Gateway Configuration
The EV kit supports a default gateway configuration.
In addition, a different Next Hop can be configured for
each bundle.
