Using the MPT 1327 Encoder
Simulated Calling Unit
The Simulated Calling Unit function uses two input fields; a 7-bit Prefix
field and a 13-bit
Ident field. This allows you to enter the prefix and identity of
the calling unit.
To test an RU the Test Set simulates a Trunking System Controller (TSC). In
some tests the Test Set simulates calls from a third party. For this purpose it is
necessary to specify the simulated calling unit’s number.
The simulated calling party could be any radio or line unit. It could also be one of
the special idents indicating, for example, a system wide call or a call from a
PABX or PSTN gateway.
The prefix is a three-digit decimal integer with leading zeros. It has the range 0
through 127 and its default value is 000.
The ident is a four-digit decimal integer with leading zeros. It has the range 0
through 8191 and its default value is 0002.
