Configuring the E1 + G.703 and T1 + DSX-1 Modules
Configuring the E1 + G.703 Module
Although E1 interfaces, including those for the G.703 port, support two frame
formats, only one option is listed if you enter the following command from the
E1 interface configuration mode context:
ProCurve(config-e1 1/2)# framing ?
Only CRC4 is listed.
By default, the frame format is E1. If your public carrier is using the E1 frame
format, you simply accept the default setting; you do not have to enter a
framing command.
However, if your public carrier is using the CRC4 frame format, enter:
Syntax: framing crc4
ProCurve(config-e1 1/2)# framing crc4
To return to the E1 frame format, enter:
ProCurve(config-e1 1/2)# no framing

Enabling TS16

TS16 is used when there is a requirement to pass through "signaling"
information in a non-proprietary manner. Two types of signaling are used for
E1-carrier lines that carry voice—Channel Associated Signaling (CAS) and
Common Channel Signaling (CCS). ProCurve Secure Routers support only
CAS. For example, they will "split" an E1-carrier line into channels 1-15 and
channels 17-31. Typically, this is not an issue because a vast majority of E1
circuits use CAS rather than CCS. (See Bradley Dunsmore and Toby Skandier,
Telecommunications Technologies Reference [ISBN 1587050366], p. 155.)
Enter the following command to enable the ProCurve Secure Router to check
timeslot 16 for the multiframes it receives on the G.703 interface:
ProCurve(config-e1 1/2)# ts16
The only time there is a signaling requirement and you do not need to configure
TS16 is when the signaling is "out-of-band," or out of the E1 circuit. In this
situation, the signaling must be handled by a separate circuit or some propri-
etary method that your PBX devices use. In other words, if a router allows the
mapping of channels 18-31 to the PBX and allows for 18 to accomplish
signaling, then the PBXs on both side of the E1-carrier line must know they
are to communicate on this channel for signaling.
