Description
Features
Digital telephone emulation
By emulating HLC-compatible models of the Meridian digital telephone, the
HLC allows telecommuters to function at their home offices as though they were
at their corporate offices. HLC-compatible models of the Meridian digital
telephone include the following models:
Meridian 2216
Meridian 2616
Meridian 2616CT (for firmware releases HLC 1.15 and later)
Meridian 3820
Variable security levels
Three security levels allow controlled access to HLC channels on a per-card
basis. See "HLC security" on page 11 for further details. The following list
describes these three levels:
Level 1: no call security
Access to the HLC's channels is not restricted.
Level 2: calling party ID (CPID)
The HLC identifies the number of the caller requesting access to one of its
channels. If that number matches the remote number of the HomeOffice
site configured for that channel, access is granted. If the number of the
incoming call does not match, access is denied.
See "SET REMOTE (S R)" on page 131 for a discussion of this feature.
Level 3: security identifier
The HomeOffice Router sends the security identifier configured for the
remote office from which the caller requests access. The HLC compares
that number to the eight security identifiers configured for the HLC. When
it finds a match, it grants access to that channel corresponding to that
security identifier. (Security Level 3 is the default security level.)
See "Security level and security identifier" on page 17.
