Here is the equivalent code, done using OO:
use warnings;
use strict;
my $host = "";
my (@T1_list, $current_T1);
my @check = grep { chomp $_; $_ } <DATA>;
for (@check) {
if (m{([0-9]/[0-9]/[0-9])$}) {
push @T1_list, $current_T1 = T1->new (INTERFACE=>$1)
}
elsif (m{pri-group}) {
$current_T1->isPRI (1);
}
}
if ( @T1_list ) {
print "T1 Controller Summary:\n\n";
print scalar(@T1_list) . " total T1 interfaces\n";
$_->PrintName for @T1_list;
print scalar(grep $_->isPRI(), @T1_list) ." total voice PRI(s)\n";
$_->PrintName for (grep $_->isPRI(), @T1_list);
}
else {
print "No T1 interfaces found";
}
{ package T1;
sub new{
my ($class, %att) = @_;
return bless ( {PRI=>0, INTERFACE=>'', %att}, $class);
}
sub isPRI{
my ($self, $val) = @_;
defined $val or return $self->{PRI};
$self->{PRI} = $val;
}
sub PrintName{
print $_[0]->{INTERFACE}, "\n";
}
1;
} # End of T1

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
