5034 DS3/DS1 Multiplexer (NYNEX Region Specific)

Multiplexing - Digital

Multiplexing is a technique that uses a single transmission facility to provide
several transmission channels, such as by sharing the time slots of the channel
(time-division multiplexing) or superimposing many frequencies at the same time
(frequency-division multiplexing) in order that many signal sources and links 
may communicate during a given time period.  This capability may include
multiplexing such as:

 - DS0 To Subrate - 
   This capability provides for the time division multiplexing of multiple
   digital data signals operating at the subrate speeds of 2.4 Kbps, 4.8 Kbps,
   or 9.6 Kbps with a 64 Kbps DS0 digital signal.

 - Multiplexing - DS1/Analog or DS0 - 
   This capability provides for the pulse code modulation and/or time division 
   multiplexing of multiple analog voice and/or multiple 64 Kbps DS0 digital 
   signals into a 1.544 Mbps data stream for the purposes of reducing the number
   of transmission links required between two points.

 - Multiplexing - DS1 To DOV - 
   This capability provides for the time division multiplexing of up to 
   twenty-four data channels into a 1.544 Mbps DS1 digital signal.  The data 
   channels are derived from the end user's access link using data over voice
   (DOV) technology.

 - Multiplexing - DS1 To DS0 - 
   This capability provides for the time division multiplexing of up to
   twenty-four 64 Kbps DS0 digital signals into a 1.544 Mbps DS1 digital signal.

 - Multiplexing - DS1 To Voice Grade - 
   This capability provides for the pulse code modulation and time division
   multiplexing of up to twenty-four 4 Khz voice grade channels into a 
   1.544 Mbps DS1 digital signal.

 - Multiplexing - DS3/DS1 - 
   This capability provides for the time division multiplexing of up to twenty-
   eight 1.544 Mbps DS1 digital signals into a 44.736 Mbps DS3 digital signal.

This service, if offered as a BSE, is associated with the Dedicated Voice
Grade and the Dedicated High Capacity basic serving arrangements.

For Ameritech, DS1 to DDS/DS0 and DS1 to Voice/Base Rate are associated with
Dedicated High Capacity Digital (1.544 Mbps) type BSA; DS3 to DS1 is associated
with Dedicated High Capacity Digital (>1.544 Mbps) type BSA.

For NX, DS1 to Voice Grade, DS1 to DS0, DS1 to DVM and DS0 to Subrate are
all associated with the Dedicated Digital 1.544 Mbps BSA.  DS3/DS1
multiplexer is associated with the Dedicated Digital 45 Mbps BSA.
