This document lays out the service level objectives for transit and delivery of NTS traffic by message precedence.

Definition of delivery

  • Routine: Reasonable belief that the message has or will reach its recipient
  • Welfare: Confirmed receipt by the addressee, or voicemail confirms name of recipient
  • Emergency, Priority: Confirmed receipt by the addressee

End-to-end transit time

From the time of origination, a Radiogram should be delivered within:

Transit time

Routine

5 days

Welfare

2 days

Priority

By the next day

Emergency

30 minutes (HXR recommended)

A Radiogram delivered after this is considered late.

Relay time

From the time a relay station receives a Radiogram, it should be either further relayed or have a delivery attempt within:

Relay time

Routine

2 days

Welfare

1 day

Priority

12 hours

Emergency

See below *

A Radiogram held longer than this is considered delayed.

* End-to-end transit time limit is 30 minutes. Each individual station must make every effort to see that the traffic moves from end to end through the system within this limit.

Commitment

Even if a service level objective has been missed, the Radiogram is still required to be moved through the system. Any relay station who accepts a Radiogram commits to moving the Radiogram further toward its recipient.

Means of delivery

The following chart illustrates the acceptable means of
delivering a Radiogram, by precedence:

Precedence

Via USPS

By leaving voicemail

By sending email/ text-message

Person to person (or designee)

Routine

Yes

Yes

Yes

Yes

Welfare

No

Yes, if greeting confirms name.

Yes, if recipient replies with confirmation.

Yes

Priority

No

No

Yes, if recipient replies with confirmation.

Yes

Emergency

No

No

No

Required

“Person to person” means by real-time two-way communication (phone, text message, radio, in-person, etc.) with the person or another person authorized to receive such messages for that person.

Exception handling

Delivery would incur cost

Description

  • Delivery would require toll call or postage

Action (by precedence)

Routine

  • HXG specified, Radiogram may be canceled. Service the station of origin.

Welfare/Priority/Emergency

  • Must make attempt at delivery, according to chart above.

Insufficient recipient information

Description

  • Cannot identify specific recipient, OR
  • No contact information: no street address, no phone, no email, no specified traffic net.

Action

  • Routine and Welfare: Cancel the message. Service the station of origin.
  • Spend time researching contact information for delivery. (Only required for PRIORITY and EMERGENCY.)
  • If cannot deliver, service the station of origin as undeliverable with ARL SIXTY SEVEN

Incorrect recipient information

Description

  • Recipient information provided, but none is correct. (Bad email, bad phone, etc.)

Action (by precedence)

Routine

  • Cancel message and service the station of origin

Welfare/Priority/Emergency

  • Service back the issue such as bad phone number (insufficient number of digits) to originator (party in Radiogram signature) and continue relaying towards destination.
  • Perform best effort to locate correct recipient contact information

Malformed Radiogram

Description

  • Preamble incomplete
  • Address, text, or signature block is missing

Action (by precedence)

Routine

  • If enough valid information exists to continue relaying, then continue by adding an OP NOTE stating that the Radiogram is malformed.
  • If there is not enough valid information to continue relaying, cancel the message and service the station of origin, if able.
  • If there is no station of origin provided, cancel the message and no further action is required.

Welfare/Priority/Emergency

  • If there is enough valid information to continue relaying, then continue by adding an OP NOTE providing your call sign and a statement that indicates the message is malformed and question its validity.
    • E.g. OP NOTE K8AMH RECEIVED MALFORMED MESSAGE FROM (SOURCE)
  • If the addressee information is invalid, then cancel the message and service the station of origin if able.
    • If no station of origin is specified, begin following SENT/RECEIVED tracking information back towards the station of origin for follow-up.

Delivery is late

Description

Message has not been delivered when the service level objective for end-to-end transit time expires, or when a relay station realizes delivery will be late, whichever occurs first. This may be caused by bad recipient information, for example.

Action (by precedence)

Routine

  • Relay or deliver, and service the station of origin noting relay or delivery took place on date/time.

Priority/Welfare/Emergency

  • Service the originator (party in Radiogram signature) regarding the situation, and continue attempting to relay or deliver. This gives the originator a chance to attempt a different method or otherwise resolve the issue.
  • If after best-effort attempts, relay/delivery is still not possible, cancel the Radiogram and service back to the originator (party in Radiogram signature).

Messages into disaster areas

Description

  • Radiogram is bound for a disaster area

Action

Routine/Welfare/Priority

  • Follow the direction of leaders within the disaster area. Attempt relay or delivery of the Radiogram, unless instructed otherwise (such as holding a message) by the leaders within the disaster area.
  • If held, service the station of origin that the Radiogram will be delayed per guidance by the leaders within the disaster area.

Emergency

  • Emergency traffic may not be held and must be moved forward towards its recipient.

Commentary

In large disasters, there are frequently embargoes on inbound non-emergency traffic for 24-72 hours. The reason for that is for the actual emergency traffic to have maximum opportunity to be passed.

Service messages

Service messages should be sent with the same precedence as the original Radiogram.

Reporting

Undeliverable messages should be reported in the station’s Station Activity Report (SAR) in a new UNDELIVERABLE (“U”) field:

  • O/# S/# R/# D/# U/# T/#
  • ORIGINATE/# SENT/# RECEIVED/# DELIVERED/# UNDELIVERABLE/# TOTAL/#

The total is the sum of Originate, Sent, Received, Delivered, and Undeliverable.

The PSHR category 2 uses this Total (including the Undeliverable count).

The SAR should be updated in a separate effort to include the reasons for the non-deliveries.

Definitions

For the purpose of measuring Service Level Objectives, a Radiogram may fall into one of the following categories:

In-transit and on-time

The Radiogram has not yet been delivered but is within the end-to-end transit time and the relay time for the traffic handler who holds it.

Delivered on-time

The Radiogram was delivered within the end-to-end transit time.

In-transit and delayed

The Radiogram has not yet been delivered and has exceeded the relay time for the traffic handler who holds it, but has not exceeded the end-to-end transit time.

In-transit and late

The Radiogram has not yet been delivered and has exceeded the end-to-end transit time, but is still within the relay time for the traffic handler who holds it.

Delivered late

The Radiogram was delivered but exceeded the end-to-end transit time.

Lost

The Radiogram has not yet been delivered and has exceeded the end-to-end transit time, and is also outside the relay time for the traffic handler who holds it.
