The TN754 circuit pack provides greater call-handling capacity for high-traffic applications and
supports the group paging feature.
Combined conversion of Modem Pooling requires two ports for each combined resource that is
supported. One port is on a TN754 circuit pack and another port is on a TN746B circuit pack or
a TN769 analog circuit pack.
TN755B neon power unit
Note:
Note: This circuit pack is no longer sold.
The TN755B neon power unit circuit pack is used with all DEFINITY servers except the
DEFINITY CSI and the G600 Media Gateway. The CSI and G600 have neon built into their 650
power supplies. The TN755B circuit pack produces 150 VDC to operate neon message waiting
lights on terminals that are connected to TN746B analog line circuit packs.
A TN755B circuit pack is required for each carrier where neon message waiting indicators are
connected.
This circuit pack and the neon message waiting function are not available on systems that use
the TN2202 ring generator circuit pack for France balanced-ringing.
TN758 Pooled Modem (2 ports)
Note:
Note: This circuit pack is no longer sold.
The TN758 pooled modem circuit pack has two conversion resources ports, such as a trunk
data module. These ports allow switched connections between digital data endpoints (data
modules) and analog data endpoints (modems). A TN758 circuit pack is required for each two
conversion resources provided with the integrated type of modem pool. The TN758 circuit pack
supports Mu-Law companding only.
