DRY solution for multiple connections?

I have multiple connections that connect to external servers via socket. However on each will do actually same thing. What is DRY solution to this?

For example:

ami1, ami2, ami3 are connected to 3 servers.

var ami1 = new require('asterisk-manager')('port','host1','username','password', true);
var ami2 = new require('asterisk-manager')('port','host2','username','password', true);
var ami3 = new require('asterisk-manager')('port','host3','username','password', true);

I have to repeat for each one

ami1.keepConnected();
ami2.keepConnected();
ami3.keepConnected();

Every each one will do actually same thing.

ami1.on('response', function(evt) {
 if () { }
 if () { }
 if () { }
});


ami2.on('response', function(evt) {
 if () { }
 if () { }
 if () { }
});

ami3.on('response', function(evt) {
 if () { }
 if () { }
 if () { }
});

Store the connections in an array:

var ami = [
  new require('asterisk-manager')('port','host1','username','password', true),
  new require('asterisk-manager')('port','host2','username','password', true),
  new require('asterisk-manager')('port','host3','username','password', true)
];

Us a loop to keep them alive

for(var i=0;i<ami.length;i++)
    ami[i].keepConnected();

(You could wrap that in a function keepAllConnected if you make multiple calls to it)

And bind events the same way

for(var i=0;i<ami.length;i++){
 ami[i].on('response', function(evt) {
   if () { }
   if () { }
   if () { }
  });
}
