Replacement exchanges for retrofit

A large number of vessels worldwide are sailing with old Vingtor-Stentofon systems. Due to instances of last-time-buy, we cannot repair or deliver spares to exchanges listed in the table below.

You can however replace all old exchanges and still use the original cabling, and in addition, originally delivered and correct working stations can still be used and will work together with a new ACM exchange.

Old exchanges are replaced with the following new ones:

SMII-216 , 224 , 232 ACM-M-A-
VMP-16-2 -32-2  ACM-M-D
VMP-48/4 , 52/4, & 80/8 ACM-48-V10
VMP-112/8 & 120/122 ACM-144-V10 or AACM-144-V10
SMP/Ericsson Businessphone ACM-IP
Mitel SX-50 ACM-IP
Marinex ACM-IP

Retrofit Request

Our policy has always been to ensure compatibility between older and newer systems.

The advantages gained from retrofitting include our latest and newest technology, reuse of existing telephones, and type-approved replacement systems. Original programming can also be used in a retrofit.

For easier processing of the retofit, please inform us of original yard, hull and IMO number, and vessel name.
