Enhanced SMPP¶
For our customers that require low level control of SMS messaging and lowest possible latency we offer our Enhanced SMPP service.
You need to reach out to our Sales team to get your credentials to use this service.
Outbound SMS SMPP¶
SMPP account details¶

Maximum instances (binds): Default 2 per SMPP account. For more connections, please contact your account manager.
IP Access¶
To access CLX SMPP server the client IP range must be announced and added to the client account.
Supported SMPP PDUs¶
| SMPP PDU types |
| bind_transmitter / bind_transmitter_resp |

Source Address¶
| Source Address | Arrive on handset | ||||
| Sent to CLX | Type Of Number(TON) | Number Plan Indicator(NPI) | |||||
| 00461234567889 | 0x00 | Unknown | 0x01 | MSISDN | 046123456789 | ||
| 01234567889 | 0x00 | Unknown | 0x01 | MSISDN | 123456789 |
| 461234567889 | 0x01 | International | 0x01 | MSISDN | +46123456789 |
| 1234567889 | 0x02 | National | 0x01 | MSISDN | 123456789 |
| CLX | 0x05 | Alphanumeric | 0x00 | Unknown | CLX |
Type of source address is defined by the source address TON and NPI parameters.
- Alphanumeric sender is limited to a maximum length of 11 characters
- MSISDN sender maximum length is 18
- To enable a handset to respond to a short code we recommend to use TON=0x00 and NPI=0x01
Destination address¶
| Destination Address | ||||
| Sent to CLX | Type Of Number (TON) | Number Plan Indicator (NPI) | ||||
| 46123456789 | 0x01 | International | 0x01 | MSISDN | ||
MSISDN Format¶
In GSM, MSISDN is built up as:
| MSISDN | CC + NDC + SN |
| CC | Country Code |
| NDC | National Destination Code |
| SN | Subscriber Number |
For further information on the MSISDN format, see the ITU-T specification E.164.
Throughput and throttling¶
Throughput is the maximum number of MT messages per second that can be sent from the SMPP account to CLX. Default value is 10 per bind. To increase the value, contact your account manager. Recommended default window size (maximum open requests) is 10. The throughput can be restricted by the capacity of the operator receiving the MT messages.
Enquire link¶
It is recommended to set your enquire_link requests to 60 seconds.
Schedule delivery time¶
In order to schedule a message to be sent in the future the optional parameter schedule_delivery_time may be added. Messages may be scheduled maximum 168 hours, one week, ahead of time. It can be specified in either absolute time format or relative time format. If this parameter is omitted messages are sent immediately. For example, the following time formats:
| schedule_delivery_time | Would be interpreted as: |
| 100312163200004+ | An absolute time March 12 2010 16:32:00 GMT+1h. |
| 000006233429000R | A relative period of 6 days, 23 hours, 34 minutes and 29 seconds from the current SMSC time. |
Time Zone¶
CLX SMSC uses UTC (Coordinated Universal Time)
MCC MNC in delivery reports¶
MCC + MNC information in SMPP delivery receipts can be included as an optional parameter. This information is passed (configurable per SMPP account whether to enable this) in a vendor-specific TLV (0x1403).
In value field you will receive the MCC MNC of the destination operator.
Example:
Optional parameter: 0x1403 (0x1403):
- Tag: 0x1403
- Length: 6
- Value (hex): 32 33 34 33 30 00 (Text: 23430n)
Result is MCC=234 and MNC=30
